Each season, the LSCA implements a milfoil control program to keep milfoil in check using a combination of spot herbicide treatments and DASH (Diver Assisted Suction Harvesting). Then, in the late Fall, a comprehensive plant survey is performed to determine how effective our efforts have been.

The report can be read directly here: 2019 - Aquatic Vegetation Management Report. This is the 16th consecutive year a plant survey has been performed on Lake St. Catherine. You can see all the previous reports, dating back to 2004 in our Links & Downloads section.

From the report: "EWM (Eurasian watermilfoil) control was excellent throughout treatment areas... This year’s spot-treatments and DASH efforts were exceptionally effective..."

Please take a look.
