HORSESHOE LAKE IMPROVEMENT ASSOCIATION: Horseshoe Lake Improvement Assoc., Rapid Response Program

Horseshoe Lake Improvement Association is sponsoring an Aquatic Invasive Species Rapid Response grant which will focus on physical removal of hybrid Eurasian Water Milfoil plants from Horseshoe Lake by scuba divers (professional and resident) and may include some small-scale chemical treatment (subject to DNR approval and permits) in fall 2007, 2008, and early season 2009. A full lake point-intercept plant survey will be completed in 2008.

Project activities include:

1) physical removal by scuba divers, 2007-2009

2) pre- and post- treatment surveying

3) small-scale chemical application (currently set at 3.5 acres or less in 2008, with the potential for a small-scale application in Fall of 2007)

4) full lake point-intercept aquatic plant survey

5) marker buoys and improved public access signage to education lake users about the hybrid EWM and to designate problem locations in the lake to minimize spread
