2.5.1 Lakes

The subwatershed includes several lakes through which Six Mile Creek flows, as well as other lakes not associated with that stream.  Tables 5 and 6 below detail the physical and water quality characteristics of the lake.  Many of these lakes are located within the Carver Park Reserve.  The HHPLS modeled water quality and established goals for nine of those lakes.  An additional four lakes had established goals in the 1997 plan but those goals were not modeled in the HHPLS.  Most of these lakes are monitored either as part of the District’s monitoring program or by Three Rivers Park District.  Little or no water quality data is available for smaller lakes scattered throughout the subwatershed.
