Everyone has a role to play
The Mitchell Lake Association is pursuing a three prong strategy to improve the lake water quality.
- Improve the quality of “in-lake” water. The Riley Purgatory Bluff Creek Watershed District has the lead responsibility for this
initiative and is focused on reducing soluble phosphorous levels by eradicating two invasive plant species (Eurasian milfoil
and Curly Leaf Pondweed) and then using a material called Alum to neutralize remaining
- Improve the quality of storm water run-off. The City of Eden Prairie has the lead responsibility for this component. The goal
is to reduce the levels of soluble phosphorous entering the lake through the storm water system (you may have noticed a
series of pipes feeding water to the lake whenever it rains) through holding ponds and the like.
- Filter water flowing into lake providing natural buffers. This is the responsibility of individual land owners and largely
accomplished by “Lakeshore Restoration” using native plants. See article below and Restoration page.
Mitchell Lake Clean-up Strategies
|To have a long term impact on
clean water we need to clean the
water already in the lake as well
as the water flowing into the lake
Everyone has a role to play in helping improve the Mitchell Lake water quality. Much of the deterioration of the lake has progressed
as a result of the increased building construction around the lake over the past 2 decades.
For example, did you know?...
- Water run-off from our lawns washes fertilizer and pesticides into the lake? Managing and minimizing the water-flow into
the lake from our lawns will help the lake tremendously.
- Water run-off from our driveways and the street in front of our homes washes directly down the storm drains, straight into the
lake. The soap used to wash our cars and the oil and coolant from the leaks from our vehicles is toxic to the lake
environment and washes straight into the lake. Repairing our leaky vehicles and having them washed at professional cars
washes that recycle their water is recommended. Another option is to wash our cars on our lawns rather than the street or
driveway for those who prefer not to have their vehicles professionally washed.
- Do your rain gutters direct the run-off from your roof straight onto your driveway and onto the street? Re-directing the gutter
run-off of rain onto your lawn as a buffer or using rain barrels to capture the rain run off is recommended. Nothing is better
for landscaping and flowers than rainwater.
- Do heavy rains collect in pools and puddles in your yard? The easiest way to help water infiltrate into the ground rather than
run off into storm sewers is by creating a raingarden. Strategically place your raingarden on a site that will intercept water
runoff. If constructed properly, the garden will drain the water within two days. Information can be obtained on line at www.
