CLEAR LAKE PROPERTY OWNERS ASSOCIATION INC: Clear Lake Native Ecosystem Preservation Project


The Clear Lake Property Owners Association in cooperation with Sawyer County Land Conservation Department will conduct an early season herbicide treatment on 4 acres of Eurasian Water Milfoil (EWM). A whole lake treatment for EWM occurred in 2001 and 2002 with good success. EWM reappeared in 2003 and the association has treated in 2006 (4.5 acres) and 2007 (4.0 acres). The association is currently working on an APM plan. The project includes the following goals: 1. An early season herbicide treatment on 4 acres of EWM in Clear Lake to control the spread. 2. Monitor the EWM throughout the year to determine efficacy of the herbicide treatment and to continue the mapping of EWM. Project deliverables include: 1. The outcome of the treatment described should show evidence of declining EWM populations in treated areas and the response of native aquatic plants. 2. EWM will be mapped prior to treatment and after treatment. The lake will be surveyed for EWM in mid July through Mid August after the herbicide treatment to determine efficacy of the treatment and regrowth. 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. 4. Obtain an APM permit prior to awarding of this grant.
