Invasive Species Committee

8-24-15  The Invasive Species Committee will be active this year protecting our beautiful lake from biological threats. In August we have started conducting a ‘mapping’ of the entire lake, noting the locations, depths and prevalence of the various species of aquatic plants present.

Our first pass was with two representatives from PLM specifically looking for Milfoil.  No large beds were noticed.  Our team is also actively looking to identify these areas.

The purpose of this is to help narrow our focus with Freshwaters Scientific Services for next years (2016) recommended treatment area – based on density of the issue.



Lake Water Quality Assessment

New assessment being done 5/2/2009

This summary is based on available summer (June through September) data in STORET (STORET is the national water quality data repository developed by the United States Environmental Protection Agency. All water quality data collected by MPCA or received from external groups is placed in STORET.) collected between 1997 and 2006.

Data Quality: Excellent
Aquatic Recreation Use Support: Fully Supporting Lakes are better than the aquatic recreation use support thresholds with sufficient data to make an assessment. These lakes are considered to be assessed for aquatic recreation and fully supporting by the MPCA.
