Lake Projects

The MPRB regularly pursues activities to prevent and reverse the effects of pollution, erosion and other factors affecting our area's lakes. A list of Water Quality Projects can be found in the MPRB Water Resources Report.

Lake Projects Include:

A pilot project to control aggressive growth of cattails in Loring Pond will begin in 2012. The goal of the effort is to begin to replace monoculture forming cattails with a diverse native plant community. The test site will be near the floating dock.

Successful alum treatments have been carried out on Cedar Lake (1996), Lake of the Isles (1997), and Lakes Calhoun and Harriet (2001). Alum (aluminum sulfate) permanently binds to phosphorus in the water column and helps to control internal phosphorus loading in a lake. Other best management practices must be used in each lakes’ watershed to control the external phosphorus load to ensure the longest possible water quality benefit.
