Making Progress For Our Lakes

In 2019, Clean Lakes Alliance’s work was focused on actions that increased community engagement and reduced phosphorus runoff into the lakes. Keep reading to learn more about our 2019 achievements. These actions could not have been accomplished without the dedication and support of our boards, committees, donors, volunteers, staff, partners, and the community.

Leaf Management

Trees are good, right?

Statewide phosphorus reduction credits for leaf collection

Urban trees provide many benefits to our communities. They help us save energy, reduce noise, and improve air quality. Trees are aesthetically pleasing, can increase property value, and provide natural homes for insects, birds, and other wildlife. Trees are also an important part of the earth’s water cycle. Transpiration from plants and trees is released into the atmosphere, and later becomes precipitation. The rain and snow return valuable moisture to our crops and forests, and the cycle continues.

However, trees can cause problems for our lakes if the leaves that fall from them each autumn are not regularly removed from streets and parking lots. When leaves collect on streets, they create a phosphorus-rich “tea” whenever it rains. The rain water passes through the leaf litter, and allows phosphorus to drain from the leaves. The leaf tea washes into storm drains and flows directly into our lakes, causing water quality to deteriorate.
