The Grindstone Lake Association is sponsoring an aquatic invasive species (AIS) control project on Little Grindstone Lake. In 2007, the AIS curly-leaf pondweed (CLP) was collected and confirmed within Lac Courte Oreilles. Since its discovery, action has been taken to control the spread and infestation of CLP with herbicide treatments in 2009, 2010, and one planned for 2011. A pioneer infestation of this plant has now been found in Little Grindstone Lake during a 2010 survey. Documentation and mapping of this new infestation showed its presence at 2.35 acres. Treatment of CLP within Little Grindstone Lake is recommended in 2011 and beyond (through 2013) to achieve control and prevent its introduction in Grindstone Lake, which is directly connected to it. Prior to treatment, a survey of the lake to verify proposed treatment areas each year will be completed and any adjustments to those or new areas will be done. Project Goals and Objectives: 1) Monitor CLP annually for a three year period on Little Grindstone Lake; 2) Effectively manage CLP; 3) Restore the native aquatic plant community; 4) Protect fish and wildlife habitat. Project Deliverables: 1) Mailing of required information packet to lakeshore owners; 2) Chemical control of CLP; 3) Monitoring data measuring effectiveness of chemical control for 2011 \2013 2013; 4) Map of CLP distribution pre & post-treatment for 2011 \2013 2013; 5) Map of potential 2012 - 2013 treatment areas of CLP. Specific conditions for this Project: 1) The WDNR will be provided electronic and hard copies of all data and or reports/plans generated as a result of this project; 2) Implement the pre and post treatment monitoring protocol (DNR May, 2007); 3) Summary report on the effectiveness of the treatment.
