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).
In late September, our contractor SOLitude Lake Management performed a comprehensive lake-wide aquatic vegetation survey to both evaluate the performance of our milfoil control efforts, and to assess the overall state of aquatic plants in Lake St. Catherine.
This is the 17th 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.
The report can be read directly here: 2020 - Aquatic Vegetation Management Report.
From the report:
"Controlling areas of dense EWM growth and maintaining it at non-nuisance levels has been the focus of recent EWM management efforts at Lake St. Catherine. The ProcellaCOR herbicide treatment this year effectively and selectively controlled EWM where used... This strategy coupled with focused DASH efforts proved to be successful in maintaining control of EWM frequency of occurrence and percent cover in both the Main Basin and Lily Pond."
Please take a look.
