The Middle St. Croix Water Management Organization (MSCWMO) monitors the water quality of lakes and streams within the MSCWMO. The MSCWMO currently monitors water quality parameters and elevation on McKusick Lake and Lily Lake, water quality parameters on Brick Pond in Stillwater, and elevation on Perro Pond in Oak Park Heights. Discharge and water quality parameters are also monitored on Perro Creek in Bayport. Water quality parameters are also monitored at Meadowlark Drive and Myrtle Street in the wetland system, which joins Lily Lake to McKusick Lake in Stillwater. The most current copy of MSCWMOs annual water monitoring report can be found here, older copies can be requested by contacting the watershed administrator.
The most current Lake Grade Charts are also available on this site.
