AGENDA ITEM 6.A.
STAFF ORIGINATOR: Marty Asleson
MEETING DATE: April 13, 2009
TOPIC: Consideration of Resolution No. 09 -20, Approving
Cost -Share in Reshanau Lake Water Quality Efforts
VOTE REQUIRED: 3/5
BACKGROUND
Over the last three years property owners living on Reshanau Lake have been
working with Rice Creek Watershed District (RCWD) to address lake water quality
problems. The residents have worked with RCWD on the creation of a management
plan for Reshanau Lake. Lakeshore property owners and the Watershed District
have been cost - sharing remediation recommendations of the plan. Initial results of
the work done have been positive. Treatment of the lake is proposed to be
continued in 2009. The City owns 1,600 feet of lake shore and given our
responsibilities as a Municipal Seperate Stormwater Sewer System (MS4) City, we
are proposing to contribute to this process.
ANALYSIS
In compliance with the Federal Clean Water Act, the Minnesota Pollution Control
Agency (MPCA) assesses the health of lakes and streams in the state. Waterbodies
that do not meet basic use standards designated by MPCA are placed on the state
303(d) "Impaired" list. Use standards are defined descriptively in the Clean Water Act
(i.e. Fishable /Swimmable), but have been assigned numeric criteria by the MPCA.
These criteria were developed to recognize inherent differences in waterbodies
caused by factors such as location (ecoregion), geologic substrate, and depth. The
MPCA considers several parameters when determining whether or not a lake is
meeting its designated uses. Reshanau Lake is classified as a Recreational Lake
and a Shallow Lake.
For Shallow Lakes (lakes less than 15 feet deep), a lake is determined to be
impaired for recreational use if a lake exceeds the following numeric standards:
Total Phosphorous 60 micro grams per liter
Chlorophyll a 20 micro grams per liter
Secchi Disk 1 meter
41111 Reshanau Lake, is classified as an impaired water by the MPCA because it has
exceeded total phosphorous standards through out the period of recorded records
•
•
(1975 to 2009). The long term phosphorous average for Reshaneau Lake is 100
micrograms per liter. With the exception of 1983, Reshaneau Lake has exceeded the
standards for Chlorophyll following the same general trend as phosphorous.
According to the RCWD, the overall water quality of Reshanau Lake is poor, and
continued treatment of curleyleaf pondweed will allow Reshanau Lake to be utilized
for recreation, with ecological health still remaining a concern.
REQUEST
A projected Lake Restoration budget for 2009 is around $40,000 for treating
curleyleaf pondweed. Property owners, RCWD and the City are all stakeholders in
restoration efforts. The City owns approximately 1,600 feet of shoreland on
Reshaneau Lake.
The Lino Lakes Environmental Board recommended that the City contribute a fair
share of our Surface Water Management account monies for the Spring of 2009 to
control curleyleaf pondweed. Monies would be used in spring of 2009 to herbicide
treat the invasive plant. It is hoped that after a few years of intensive treatment,
regeneration of new curleyleaf pondweed will have been arrested. Other
management issues can than proceed to improve water quality to a "swimability"
status.
Share cost is approximately $200 per lot. The City owns the equivalent of
approximately 8 lots for a cost of $1,600.00.
RECOMMENDATION
Staff recommends adopting Resolution No. 09 -20 supporting the contribution of
$1,600 from the Surface Water Management Fund for curleyleaf pondweed
treatment in Reshanau Lake for 2009.
