Why is stormwater a problem?
We tend to think that large industrial polluters cause most water pollution, but this is not the case. We are the real culprits. The Environmental Protection Agency (EPA) has determined that up to 70% of the pollution in our surface waters is carried there by stormwater runoff. Some studies show that about 50% of that pollution comes from individuals and homeowners, due to yard care, yard waste, and chemical pollution from household activities.
When it rains, water runs off of our roofs, parking lots, streets, and lawns, instead of soaking into the soil the way it did before development. This water, along with everything it picks up along the way, ends up in storm sewers and ditches that discharge into the lake. Salt from roads, pet waste, lawn nutrients, spilled gas, oil and other pollutants are all washed into our lake water.
Will rain gardens breed mosquitoes?
No. Mosquitoes needs 7 to 12 days to lay and hatch eggs, and standing water in the rain garden will last for a few hours after most storms. Mosquitoes are more lilely to lay eggs in bird baths, storm sewers, and lawns than in a sunny rain garden. Also rain gardens attract dragonflies which eat mosquitoes.
How is a rain garden constructed?

stormwater management regulations must be met.
You can put a rain garden just about anywhere. In a low area of your yard, a complex of plants and soil will absorb a lot of rain.

What plants can I put in a rain garden?
Many beautiful plants, trees and shrubs can be planted in a rain garden. We recommend species native to to our region, but other cultivated non-native species can be very beautiful, too. Just NOT Purple Loosestrife!
