Every little bit helps.
Runoff is the biggest threat to Monona Bay's water quality. For homeowners, many simple common-sense strategies can reduce runoff. For commercial and institutional residents in the watershed, the challenges are greater.

Hard surfaces, such as parking lots and streets are an enormous source of runoff. A one-acre parking lot produces about 16 times as much runoff as a one-acre meadow. The use of permeable hard surfaces is one way to address this problem. Rain gardens and infiltration trenches are another. For example, the Department of Defense has constructed infiltration trenches in their massive parking lots at the Pentagon.

Water quality is vital to our recreational enjoyment of Monona Bay. Improving water quality will take time and dedication.
