Maple Cove is a 17-acre Conservancy parcel on the northwest side of Deer Lake. Donation of this property by the Miller family allowed treatment of runoff and prevented back lot development in an area that drains to Deer Lake.
A deep ravine previously carried pollutants from agricultural fields directly to Deer Lake. A sedimentation basin now installed on the property captures field runoff allowing it to soak into the soil. Allowing infiltration of runoff water not only captures agricultural pollutants but also feeds the springs that flow into the lake along its western shore. The fields were planted with eighty prairie species from seed collected within 50 miles of the site. A walking trail is open to the public.
