EXECUTIVE DIRECTOR’S REPORT
8.a. 2024 Well Pumping Report & 2025 Well Pumping Record through February
The total amount of water pumped from wells in 2024 is 10% lower than in 2023. The decrease in water
usage is likely due to the abundant precipitation received in the spring.

REGULAR MEETING PROCEEDINGS
MARCH 31, 2025
Director Egger noted that with the new well 17, a new appropriation permit will be required. That process
will take place after the well is built to determine capacity.
Commissioners asked about potential upgrades to the splash pad, specifically the addition of a chlorinated
recirculation system. Staff responded that the Parks & Recreation Department is currently in the planning
phase of a Central Park redesign. A recirculation system for the splash pad will be included in the scope
and budgeting process but will require City Council approval.
8.b. 2024 City Water Usage with 10-Year Trend Chart
Director Egger noted that government water usage in 2024 was below 38 million gallons—the lowest
amount recorded in the past 5 years.
It was also noted that there is currently insufficient data to assess water usage at the Public Works &
Police Building. Several years of data will be needed to establish a reliable estimate of its annual
consumption.
8.c. Top 10 Water Users 2024
Staff pointed out that there are no changes to the top 10 water users in the city for 2024. Some of these
top users include multifamily residential properties, not just industrial or commercial accounts.
When current residential rates were applied to the usage levels of the top 10 users, billing amounts
increased slightly. This analysis may help inform future utility rate modeling for 2026. Commissioners
requested further evaluation of how residential water rates impact high-, mid-, and low-volume
commercial and industrial users.
Commissioners also inquired about the 2021 tier 4 rates, noting that rate changes appeared to have
occurred in some areas but not others. Staff will review the 2021 meeting minutes and rate models for
clarification.
8.d. Well 17 Update
Drilling mobilization for Well 17 began last week. The contractor is currently drilling the pilot hole and
collecting geological samples. Once this phase is complete, full-width boring of the well will begin. Staff
plan to schedule a site visit for commissioners later in the process.
A separate contract for the well house structure has been awarded, but construction will not begin until
drilling is complete. Well 17 is expected to be operational by summer 2026.
8.e. Action Item / Issues list
i. Presentation by Dan Schultz of the Parks & Rec Department on the Central Park renovation at
a future commission meeting.
ii. Confirm deadline of 3/28/2025 for the Met Council Equity-Focused Water Efficiency Grant
Pilot Program.

UTITLIY COMMISSION
Quarterly Water Efficiency Rebate Update:
The City of Rosemount was awarded a Water Efficiency Grant from the Metropolitan Council
(MCES) in the amount of $27,000 for the 2024-26 grant cycle.
As part of this program, the following rebate amounts are allowed:
•$50 for Water Sense Toilets
•$150 for Energy Star Washers
•$150 for Energy Star Dishwashers
•$150 for Water Sense Irrigation Controllers
•$200 for Irrigation system audits
The Vermillion River Joint Powers Organization (VRWJPO) ended its program partnering with cities
in the county to provide funding for multi-family residential properties for low-cost irrigation audits
and improvement cost share grants. The City Council approved the Irrigation Efficiency Grant
Program as a replacement at its August 20, 2024, meeting. The City is working on reaching out to
HOAs and has received some interest in the updated program.
Table 1 provides a summary of the entire rebate program activity through Q1 2025.

to install projects on their property to improve stormwater quality and reduce runoff volume. In March
2020, City Council approved the Stormwater Rebate Policy and established a maximum amount of
$5,000.

APPROVED BY: NAE
RECOMMENDED ACTION: Informational only
BACKGROUND
Staff continued to collect quarterly tap water samples from several dozen locations throughout the
City over winter quarter (February/March) and earlier this spring (early May). Samples were collected
from as many properties as were available on account of access to a running tap at the property
(winter conditions) and as staff had availability to make the rounds, so although most properties were
sampled, there were some for which a sample was not collected.
As with previous rounds of sampling, the City measured manganese concentrations for all samples and
also sent companion samples to Minnesota Valley Testing Lab (MVTL) for independent third-party
analysis.
• For the Commissioners' information, the following materials have been included:A summary
table of all results from the February/March (Q1 2025) and May (Q2 2025) sampling periods,
showing manganese concentration data from both the City (orange) and MVTL (blue) analyses
• A chart plotting the MVTL analysis results for both Q1 and Q2 samples
• Tables detailing the pumping contributions from each well on the sample collection days
• The sample results reports from MVTL for Q1 & Q2
Staff will continue to conduct an additional one to two quarterly rounds of samples to get a complete
annual cycle's worth of data, which will then be taken in totality as a basis for discussion and
consideration of next steps by the City.

BACKGROUND
The City of Rosemount (City) has been monitoring water quality and water levels in select ponds since
2009 to provide the city with data it uses to help guide stormwater water management activities. The City
has monitored the following ponds for the last several years, including in 2024:

Basins are monitored for total suspended solids (TSS), total phosphorus (TP), ortho-phosphate (OP),
chloride, and nitrogen (new in 2022). Water levels are used to evaluate level fluctuations, runoff volumes,
and infiltration rates.
Here are some key takeaways from the report:
• Water level monitoring shows Wachter Pond is consistently exceeding its management elevation
Page 82 of 199
by several feet, and Shannon Pond has had an increasing trend over the last 10 years and
frequently exceeds its management elevation.
• Water levels at Bloomfield Pond, Shannon Pond, and Wachter Pond have remained stable and not
dropped despite four years of drought.
• Basins with higher estimated runoff volumes have tended to be those with higher impervious
surface coverage or that receive large amounts of flow from upstream basins.
• Estimated city-wide infiltration rates have exceeded the estimated infiltration rate from the 2009
Non-Degradation Report, but have shown a decreasing trend until 2023 and 2024.
• The city-wide long-term median TSS shows overall effective treatment in monitored basins.
• The city-wide long-term median TP is within the anticipated range for treated stormwater.
• OP on average has been 18 percent of the TP that was observed, which is much lower than the
expected range when the source is plant litter and lawns.
• There has been an increasing trend in chloride concentrations since 2014.
• Select city ponds have periodically exceeded the chronic or acute chloride standard; Erickson
Pond was the only pond to exceed the chloride chronic standard in 2024.
• Nitrate concentrations are well below the proposed chronic nitrate standard for Class 2B waters.

1. EXECUTIVE SUMMARY
The City of Rosemount (City) has implemented a water quality monitoring program since 2009 that
provides the city with empirical data that can be used to help guide stormwater water management
activities. The City has monitored between 10-12 basins annually for water quality parameters including
total suspended solids (TSS), total phosphorus (TP), orthophosphate (OP), chloride, and nitrogen (new in
2022). Water levels are also monitored to evaluate level fluctuation, runoff volumes, and infiltration rates.
This report provides a summary of the results of data collection activities from 2014-2024.
The monitoring data is used to fulfill multiple MS4 program requirements in minimum control measures
(MCMs) 5 and 6 related to inspection, long-term operation, and maintenance of infiltration Best
Management Practices (BMPs). The water level data is used to observe fluctuations in basin levels,
especially landlocked basins, to protect adjacent structures from flooding risks. Observed infiltration rates
were compared to infiltration results outlined in the City’s Non-Degradation Report. Runoff ratios for the
individual basins are calculated using localized rainfall data and level data and were evaluated against
impervious surface percentages and land use types.
Water quality is utilized to determine if basins are meeting anticipated pollutant removal efficiencies for
total suspended solids and total phosphorus. Additionally, snowmelt sampling is conducted to assess
winter pollutant concentrations associated with snowmelt runoff.
Data collection activities were conducted from May through October each year, with snowmelt sampling
occurring during the winter. Basins that are monitored for level are equipped with an electronic monitoring
device that records continuously. Event-based rainfall is also monitored at several locations within the
City to provide localized rainfall totals. Water quality samples are collected as grab samples monthly.
A summary of the notable findings from the monitoring activities include:
Water Level Monitoring
Landlocked basins Location 9 (Watcher) and Location 10 (Shannon) have shown a significant
increasing trend in minimum, maximum, and average water levels in past years monitoring,
but saw lower levels starting in 2021 and continuing through 2023. That trend was reversed
in 2024, with the minimum, maximum, and average water levels increasing at both locations.
Management activities at those sites should be evaluated to ensure adequate storage
capacity and acceptable water levels at those sites.
The long-term City-wide Rainfall to Runoff (R/R) ratio was 0.21, which indicates that, on
average 21 percent of rainfall ends up as runoff within the city.
Infiltration monitoring has shown a 9-year average infiltration rate of 0.063 inches per hour
(in/hr) City-wide. The 2024 infiltration rate of 0.095 in/hr was above the 9-year average.
Water Quality Monitoring
2024 monitoring season saw low amounts of rain and similar concentrations of pollutants at all locations,
except for chlorides, which was higher at all locations.
TSS
The long-term median concentration for TSS City-wide was 12 milligrams per liter (mg/L).
The long term median TSS concentration ranged from 6 mg/L at Location 1 (Marcotte) to 34
mg/L at Location 10.
TP
The long-term median TP City wide was 0.14 mg/L which is lower than the anticipated range
for treated stormwater of 0.15 to 0.2 mg/L.

Rosemount Water Quality Monitoring Program – 2024
City of Rosemount, MN
WSB Project No. 025291-000 Page 2
OP
OP was noticeably greater at Location 6 than the other monitored basins, with a long-term
median 0.091 mg/L. The next highest is Location 3 (Trailer Park Pond) with a long-term
median of 0.050 mg/L. The drainage area to that basin includes a large area of open park
space as well as drainage from a splashpad.
Chloride
2024 snowmelt sampling saw only Location 6 to exceed the 4-day chronic chloride standard
(230 mg/L). In 2023, Location 6 snow melt sampling exceeded the maximum standard of 860
mg/L
No other locations exceeded the 4-day chronic standard in 2024.
Locations 6 and 9 contain areas of commercial and/or downtown land uses within their
drainage areas, which is typically associated with higher salt use in the winter. This is
reflected in the elevated chloride concentrations observed within the basins.
Nitrate
Nitrate monitoring was new for 2022.
Nitrate levels were very low throughout 2024.
The highest nitrate concentration was 0.244 mg/L at Location 9 in February. The MPCA
proposed chronic nitrate concentrations for Class 2B waters are 8 mg/L.

2. INTRODUCTION
The water quality monitoring program for the City of Rosemount (City) includes seasonal water data
collection at select stormwater basins in the City. The data is used to fulfill multiple MS4 program
requirements in minimum control measures (MCMs) 5 and 6 related to inspection, long-term operation,
and maintenance of infiltration Best Management Practices (BMPs). The water quality monitoring
program provides the City with empirical data that can be used for the following purposes:
Guide Watershed and City Stormwater Plan Updates and discussions with observed runoff
volumes and infiltration and evaporation rates.
Identify potential areas to receive regional volume reduction credit through stormwater reuse
applications.
Validate pond treatment efficiencies from the SWAMP program with sampled Total
Suspended Solids and Total Phosphorus concentrations.
Supporting conclusions in the City’s Non-Degradation Study with observed infiltration and
evaporation data.
Creating a baseline for discharge volumes and pollutant loading assumptions of possible
future Total Maximum Daily Loads (TMDLs) in the Vermillion River and Mississippi River.
Assessing winter pollutant concentration associated with snowmelt runoff.
Water level and water quality data were collected as part of this monitoring program to analyze basin
performance and watershed characteristics. Water level and precipitation data was used to calculate
runoff volumes for various storm events and to develop a relationship between rainfall and runoff for the
drainage area. Water level data is utilized to generate infiltration and evaporation rates during periods of
no rainfall. To evaluate these parameters, electronic monitoring equipment was used to continuously
measure system water levels and rainfall amounts. The ponds selected for monitoring are summarized in
Table 2.1 below which also includes a description of basin and drainage area characteristics. In Table
2.1, Birger Pond was only monitored for snowmelt samples and has had water quality data collected by
the Citizen-Assisted Monitoring Program (CAMP). The pond location maps are provided in Attachment A
and include the drainage area and land use information.

3. PROCEDURES AND METHODOLOGY
This section outlines the procedures and methods followed to perform monitoring and data analysis.
3.1. Water Level Monitoring
Pond level monitoring was completed using automatic level loggers that record water surface elevation at
an interval of one reading per hour. During equipment installation at the beginning of each monitoring
season, a reference elevation is collected to convert monitored water depth into water surface elevation.
Monthly data retrievals and equipment maintenance are completed in conjunction with water quality
sampling activities.
Image 3.1: Level Monitoring Configuration
The water level data is utilized to calculate rainfall to runoff (R/R) ratio for each rainfall event. A R/R ratio
represents the proportion of rainfall that is not infiltrated or evaporated and thus ends up as runoff. The
purpose of calculating an R/R ratio is to establish a relationship that can be used to estimate runoff for a
drainage area. The data can be used to calibrate stormwater models, compare runoff produced by
different drainage areas, and to analyze changes in runoff volume over time for a specific basin. A R/R
ratio is calculated by estimating the volume received by the basin from the change in water level over the
pond surface area. The volume is then converted to inches of runoff per acre of contributing watershed
area. The annually calculated R/R ratio is the linear regression of the event-based R/R calculations for
each year.
The water level data is also utilized to calculate infiltration and evaporation rates for the monitored basins.
This data can be used to calculate actual volume infiltrated, and the trend data can be used to help
identify basins in need of maintenance. The infiltration rates are calculated by change in water level over
time, when water levels are below outlet elevations (basin is not discharging). The rates that are
calculated include infiltration and evaporation.

3.2. Water Quality Sampling
Water quality samples were collected as grab samples from Locations 1-10 monthly, approximately May
through October of 2024. Winter snow melt sampling was also completed at basins 1, 5, 6, 7, 9, and Birger
Pond. The samples were targeted for the mid-water column, to be representative of concentrations within
the basin. Snow-melt sampling followed the general procedures outlined in the MPCA Guidance (MPCA,
2020). The samples were collected using an extension rod sampler which was rinsed three times before
collection. The samples were then transferred into laboratory provided containers with the appropriate
preservative, placed in a cooler on ice, and delivered to Tri-City Laboratory in Bloomington, MN. The
samples were analyzed for the parameters listed in Table 3.1 below. CAMP data collected on Birger Pond
was collected by volunteers at two-week intervals from April through mid-october. Water Quality samples
were collected over the deepest spot on Birger Pond, along with temperature and Secchi disk
measurements.

4. RESULTS
4.1. Water Level Monitoring
Stormwater runoff from areas within the City of Rosemount is directed to various lakes, ponds, or
depressions within the city, many of which are landlocked. Location 6, Location 7, Location 9, and
Location 10 are basins that are closely monitored because in addition to localized runoff, these basins
also receive discharge from upstream stormwater features, which makes them susceptible to significant
water level increases during major events. The City has outlined specific management elevations and
activities at these sites to ensure adequate capacity is maintained to effectively store and treat
stormwater runoff.
Image 4.1: Water Level Monitoring (Location 6)
The water level data that has been collected was evaluated against the management elevations that were
established for each of the basins. 2024 water level charts with hourly rainfall data are included in
Attachment B. Table 4.1 below includes a summary of the minimum and maximum water elevations that
have been observed over the 2024 monitoring season at each site, as well as applicable management
elevations and outlet details.

The water elevation range over the 2024 monitoring period at Location 6 was 2.22 feet and Location 7
was 2.25 feet. There has been no indication of an increasing trend in either average or maximum levels at
those locations. Based on the monitoring data collected to date, these basins have been observed to
provide adequate storage and infiltration of the runoff that has been conveyed. Location 6 receives
discharge from an adjacent splash pad during summer months. On average, 10.7 million gallons per year
have been discharged from the splash pad and infiltrated by the basin. The daily level increase and
subsequent decrease because of the splash pad discharge in 2024 was approximately 0.19 feet. Long
term water trends for Location 7 are shown in Chart 4.1.
Chart 4.1
Location 9 levels have consistently exceeded its management elevation of 910 feet amsl. The average
water level in 2024 was 915.1 feet amsl and was consistent with the average water level for 2020. The
average, minimum, and maximum levels in 2024 changed from 2023. In 2024, the average water level
Page 92 of 199

City of Rosemount, MN
WSB Project No. 025291 Page 8
increased from 913.5 in 2023 to 915.1 in 2024. This increase is also represented in the maximum and
minimum water levels for the pond compared to 2023. The water level in pond 9 is the highest since 2018
when the average water level reached 915.3 ft. Long-term trends for Location 9 are presented in Chart
4.2.
Chart 4.2
Location 10 has shown an increasing trend in the minimum, maximum, and average water levels since
2014, although 2021 through 2023 had a decrease in levels from previous years. This decrease could be
due to lower-than-average precipitation for the last three monitoring seasons. The average, minimum,
and maximum levels for 2024 increased from 2023. Location 10 long-term trends are presented on Chart
4.3 below.
Chart 4.3
The average, minimum, and maximum water level at Location 10 increased in 2024. Location 9 reached
the required level of 916 ft for 504 total hours. The level at Location 10 was above the 920-management
required level for a total of 2,931 hours. These sites have consistently been above management levels
Page 93 of 199

and should be evaluated for alternative management strategies that aim to restore the capacity of the
basin.
4.2. Rainfall to Runoff Calculations
R/R ratios, also known as runoff coefficients, were calculated for each basin in 2024 and the results are
presented in tables and charts in Attachment B. During the 2018 Surface Water Management Plan
(SWMP) update, the drainage areas for the basins were reevaluated. As a result, the R/R ratios were
recalculated for the previous years (2014-2017), with the updated drainage information. The annual R/R
ratios provided below are based off the linear regression of individual R/R events (Chart 3.4). The long-
term average R/R ratios are presented on Table 4.2, below.

A larger R/R ratio is indicative of less storage and infiltration within a drainage area, and consequently, a
greater proportion of runoff being produced. Drainage areas that have a larger percentage of impervious
surface will typically exhibit a higher R/R ratio. Event-based R/R ratios can vary greatly depending on
rainfall intensity and the antecedent soil moisture.
The City-wide R/R ratio has not varied much over the years ranging from 0.19 in 2024 to 0.25 in 2017,
with the long-term average being 0.21. Of the monitored basins, Location 3 has consistently exhibited one
of the greatest R/R ratios since 2014, which has shown that on average, 41 percent of the rainfall within
that drainage area ends up as runoff. The Location 3 drainage area consists of 37 percent impervious
Page 94 of 199
Rosemount Water Quality Monitoring Program – 2024
City of Rosemount, MN
WSB Project No. 025291 Page 10
surface which is slightly above the average of the monitored basins (34 percent). The predominate land
use at Location 3 is low density residential (98 percent), with the remaining area designated as open park
space.
Other basins that have shown higher R/R ratios include Location 1 and Location 8 having a long-term R/R
ratio of 0.41 and 0.32, respectively. The drainage area for Location 1 consists of 17 percent impervious
surfaces, which is the lowest percentage of the monitored basins. The higher R/R can be attributed to
variability in upstream runoff contributions from basins that discharge to Location 1 that are not within the
immediate drainage area. Location 8 consists of 43 percent impervious surfaces, includes drainage from
a significant portion of commercial land use along 150th St. SW (CSAH 42). Location 8 had the second
highest R/R ratio in 2024.
Location 2 (1486) has produced the lowest R/R ratio almost every year monitored with a long-term
average of 0.08. The Location 2 drainage area is 25 percent impervious, which is the 2nd lowest of the
basins monitored. The predominate land uses include Transitional Residential (67 percent) and Rural
Residential (31 percent). The long-term rainfall to runoff ratios can be seen in Chart 4.4 below.

4.3. Infiltration Rate
The water level data was utilized to generate an infiltration and evaporation rate for the basins when
water levels were below outlet and pump elevations. The 2024 infiltration rates are presented in the
tables included as Attachment B. A long-term summary of the average infiltration rates is provided in
Table 4.4 below. The infiltration rates were evaluated against the estimated rates identified in the City’s
Non-Degradation Report that was completed in 2007. The rates described below are inclusive of both
infiltration and evaporation.
Table 4.4: Infiltration Rate Summary
Infiltration monitoring has shown a long-term average infiltration rate of 0.060 in/hr. City-wide. Annually,
infiltration rates have ranged from 0.200 in 2024 to 0.007 in 2022. The City’s Non-Degradation Report
utilized an average infiltration rate of 0.030 in/hr. This was developed by taking the average infiltration
rates that were identified for type D soils during a literature review. As shown above, the City-wide
average infiltration rate has exceeded the City’s Non-Degradation Report rate every year that monitoring
has been conducted.
In 2024, Location 11 (1720) had the greatest infiltration rate at 0.200 in/hr. The greatest long term
average infiltration rate of 0.127 in/hr occurred at Location 3. Location 8 had the lowest infiltration rate in
2024 and continues to have the lowest long term average infiltration rate at 0.020 in/hr.
At Location 8, accumulation of sediment and vegetation growth near the pond outlet has increased the
elevation needed for the pond to discharge from an elevation of 929.70’ to 930.05’.
4.4. Water Quality Results
The water quality data collected to-date is provided for each monitoring location in the Tables and Charts
included as Attachment C. Water quality sampling has consisted of growing season sampling, roughly
April – October. Appropriate data collected has been added to the long-term calculations. The long-term
median growing season concentration (excluding snow melt samples) for each of the evaluated
parameters is presented in Table 4.5 and the 2024 growing season average concentrations in Table 4.6

The findings of the water quality sampling are summarized within this section by pollutants. The results
are presented in box and whisker plots which provide a visual representation of the sample distribution
and show important statistical data. A summary of the metrics presented on the box and whisker plots is
shown on Image 4.2. Individual data points that lie outside of the minimum and maximum values are
outliers.
Image 4.2 – Box and Whisker Plot Legend
Total Suspended Solids
Sources of TSS in stormwater include deteriorated pavement, vehicle exhaust emissions, vehicle parts,
building and construction material, road salt, road paint and pedestrian debris, soil material, plant and leaf
litter, and atmospheric deposition of particles. Suspended solids transported into rivers and lakes
eventually settle on the bottom, and over time this accumulated sediment can clog and alter the
topography of bodies of water.
City-wide, the TSS long term median is 12 mg/L, which is unchanged from the previous year’s long-term
median. Median TSS values range from 6 mg/L at Location 1 to 34 mg/L at Location 10. The greatest
variability in TSS concentrations have been seen at Location 7, Location 8 and Location 10, as
demonstrated by larger inter quartile ranges (IQR), depicted as the “box” on Chart 4.5 below. The IQR
reflects the middle 50 percent of the data collected at that site. Location 1 (6 mg/L) and Location 3 (7
mg/L) have the lowest long-term median TSS and are comprised of predominately low density residential
and commercial land uses. Location 10, with the greatest long-term median TSS concentration, consists
of predominantly low-density residential land use.
The City’s Non-Degradation Study presented an estimated event mean concentrations for TSS based on
land uses, which were derived from a review of applicable research documents. These concentrations
included 50 mg/L for open space, 140 mg/L for single family residential, and 215 mg/L for agricultural land
uses. Basins built to NURP design standards are anticipated to provide TSS treatment efficiencies of 85
percent. The City-wide TSS median of 12 mg/L shows that overall, the monitored basins have provided
effective TSS treatment.

WSB Project No. 025291 Page 14
Chart 4.5 – Total Suspended Solids
2024 Total Suspended Solids
In 2024, the City-wide TSS average concentration was 21 mg/L and had a range from 7 mg/L at Location
1 to 39 mg/L at Location 8. 2024 TSS values were higher than 2023 which had a city wide average TSS
concentration of 12 mg/L.
Total Phosphorus
Sources of phosphorus in urban runoff include plant and leaf litter, soil particles, pet waste, road salt,
fertilizer, and atmospheric deposition of particles. Lawns and roads account for the greatest loading,
which has shown to contribute about 80 percent of total and dissolved phosphorus (Waschbusch et. al
1999). Phosphorus has a direct effect on plants and algal growth in lakes and is one of the leading
causes of deteriorating lake water quality.
City-wide, the average TP long term median is 0.14 mg/L, ranging from 0.07 mg/L at Location 4 (1687) to
0.22 mg/L at Location 10 and Location 6. Additionally, Location 5 and 4 have the smallest IQR, which
indicates that the sample concentrations were closer to the median, with less overall variability. The
greatest variability in TP concentrations was seen at Location 7. Chart 4.6 shows the long-term TP
averages and variability.
Typical concentrations of TP for untreated stormwater are 0.22 mg/L for commercial purposes, 0.30 mg/L
for residential, and 0.32 for cropland land uses. Basins built to NURP design standards are anticipated to
provide TP treatment efficiencies of approximately 60 percent. The City-wide average median of 0.14
mg/L TP is within the anticipated range for treated stormwater (<0.20 mg/L).

WSB Project No. 025291 Page 15
Chart 4.6 – Total Phosphorus
2024 Total Phosphorous
During the 2024 growing season, the City-wide TP average concentration was 0.13 mg/L, which is down
from 0.15 mg/L in 2023. Location 6 and 8 had the highest average concentrations of TP at 0.20 mg/L and
location 4 had the lowest concentration of TP at 0.07 mg/L.
Ortho-Phosphate
Orthophosphate is the dissolved component of total phosphorus that is readily available for algal
production. Dissolved phosphorus typically accounts for about 45 percent of total phosphorus but can
exceed 50 percent when the source is plant litter and lawns, and as low as 25 percent when the source is
predominantly sediment (Waschbusch et. al, 1999).
City-wide, the OP long term average median is 0.024 mg/L, ranging from 0.010 mg/L at Location 2,
Location 4, Location 5, Location 9, and Location 10 to 0.091 mg/L at Location 6. Location 6, with the
greatest observed OP, receives water from a splash pad and contains open park space within a
significant portion of its drainage area. For all monitoring locations OP on average, has been 18 percent
of the TP that was observed which is much lower than the expected range when source is plant litter and
lawns. Chart 4.7 shows the long-term OP averages and variability.

Chart 4.7 – Ortho-Phosphate
2024 Ortho-Phosphate
During the growing season of 2024, the City-wide OP average concentration was 0.024 mg/L, which is
equal to the long-term average. Many locations saw lower values in OP 2024 compared to 2023. Location
1 was the only location that had a higher concentration of OP at 0.036 mg/L in 2024 compared to
0.013mg/L in 2023.
Chloride
Chloride is a key component of road salt, which is soluble and highly mobile in water. When snow and ice
melt, the salt that has been applied to icy roads, parking lots, and sidewalks is conveyed with it into
surface water and groundwater. Elevated chloride levels can affect our drinking water supplies and can
be toxic to aquatic organisms. The chloride water quality standard for 2B lakes is a 4-day average of 230
mg/L for chronic toxicity and 860 mg/L as the maximum standard toxicity. These standards are used for
Public Waters which include Location 9 and Birger. The other monitoring locations are only provided for
comparative purposes.
Chloride sampling was implemented City-wide in 2016, with snowmelt sampling being conducted at select
basins in 2016 and then again from 2018 through 2024. The chloride results are plotted on Chart 4.8
below. Additionally, chloride charts for the individual basins are included as Attachment C.

WSB Project No. 025291 Page 17
Chart 4.8 – Chloride Concentrations
Location 6 exhibits significant snowmelt concentrations for chlorides, but those concentrations readily
decreased over the summer months. Location 6 drainage area contains parking lots and pathways that
may contribute to its higher concentration levels during winter/spring. This was the case in 2024,
Location 6 snowmelt samples were above the chronic standard, but decreased over the summer months.
Location 6 was the only pond do exceed the chronic standard in 2024. Location 8 has shown snowmelt
and spring routine samples that have exceeded the chronic standard but were below the chronic standard
throughout the entirety of the monitoring season.
In addition to elevated snowmelt chloride levels, Location 9 has the greatest growing season chloride
concentrations of all the basins. One notable observation is that Location 9 chloride levels decreased
throughout the growing season, which hasn’t been case in previous years. The increase in these
concentrations in the fall could indicate that the basin is stratified over the summer.
Locations 6, 8, and 9 all contain areas of commercial and/or downtown land use within their drainage
areas, which are typically associated with higher salt use in the winter. This is reflected in the elevated
chloride concentrations observed within the basins. Location 6 and Location 9 are both landlocked, which
results in pollutants being concentrated within those basins and not discharged downstream.
The remaining monitoring locations have not had an exceedance of chloride water quality standards
during routine sampling and have not shown any notable increasing trends with respect to chloride levels.
2024 Chloride
During 2024, the City-wide growing season chloride average concentration was 29.9 mg/L, which is less
than the long-term average of 56.1 mg/L. Location 6 had the highest average chloride concentration at
99.6 mg/L. Location 1 had an average of 46.3 mg/L. Most locations saw consistent chloride levels
throughout the year.

Nitrate
Nitrogen is a nutrient that is necessary for plant and algae growth. Most nitrate (a form of nitrogen) in
Minnesota waters comes from agriculture practices while only one percent is estimated to come from
urban stormwater (MPCA 2013). At increased levels, nitrates can be detrimental to aquatic life, cause
algal blooms, and possibly dangerous to human health. In 2022, the MPCA proposed nitrate criteria to
protect aquatic life. The proposed chronic 4-day standard for Class 2B lakes is 8 mg/L. Nitrate monitoring
was new to the City’s monitoring program in 2022.
2024 Nitrate
During the 2024 growing season, the City-wide nitrate average concentration was 0.036 mg/L. Location 9
had the highest average level of nitrate at 0.092 mg/L, which is far below the proposed standard of 8
mg/L. Long term nitrate sampling results are plotted on Chart 4.9 below.

5. CONCLUSIONS AND OBSERVATIONS
Eleven basins were monitored for water level and water quality to provide the City with empirical data that
can be used to help guide stormwater management activities. A summary of the notable findings from the
monitoring activities are provided below:
Water Level Monitoring
Landlocked basins Location 9 and Location 10 have shown a significant increasing trend in
minimum, maximum, and average water levels over the long-term monitoring period, but saw
lower levels in 2021 through 2023 due to low precipitation totals (drought conditions).
Despite drought in September and October 2024, minimum, maximum and average water
levels increased from 2023.
Even with four years of drought, the average water level at Locations 7, 9 and 10 has
remained stable and not dropped significantly since 2021. Management activities at those
sites should be evaluated to ensure adequate storage capacity and acceptable water levels
at those sites.
The long-term City-wide R/R ratio was 0.21. This remains consistent from the previous year.
Long term R/R ratios varied by site from 0.40 at Location 1 to 0.05 at Location 2. Those sites
consisted of 37 percent and 25 percent impervious surfaces, respectively.
Infiltration monitoring has shown a long-term average infiltration rate of 0.063 in/hr City-wide.
Since 2015, infiltration rates have consistently decreased, until 2023 (0.066 in/hr) and 2024
(0.095 in/hr).
Water Quality Monitoring
In general, higher stormwater pollutant levels were observed at Location 6, Location 9, and Location 10.
This is largely due to these basins being landlocked and pollutants staying concentrated within the basin
and are not transported downstream.
TSS:
The long-term average median concentration for TSS City-wide was 12 mg/L. The long-term
median TSS concentration ranged from 6 mg/L at Location 1 to 34 mg/L at Location 10.
TP:
The long-term average median concentration for TP City wide was 0.14 mg/L which is slightly
below the anticipated range for treated stormwater of 0.15 to 0.20 mg/L. The long-term median
TP concentration ranged from 0.07 mg/L at Location 4 to 0.22 mg/L at Location 6 and 10.
OP:
The long-term OP was noticeably greater at Location 6 than the other monitored basins. In 2024,
Location 6 has the highest long-term median of OP, 0.091 mg/L.
Chloride:
Locations 6 and 9 contain areas of commercial and/or downtown land use within their drainage
areas, which is typically associated with higher salt use in the winter. Location 6 tends to see
high levels during winter sampling, while Location 9 has the highest long term median chloride
levels at 77.2 mg/L. Location 9 is a landlocked basin that may be contributing to the elevated
chloride levels throughout the monitoring season.
There has been an increasing trend in chloride concentrations since monitoring began in 2014
Nitrate:
Nitrate monitoring was new in 2022. The MPCA proposed chronic nitrate concentrations for
Class 2B waters are 8 mg/L.
Nitrate levels were very low throughout the year, with the last sampling of the year having the
highest levels overall. The highest nitrate concentration was 0.034 mg/L at Location 3.
