|For the sixth consecutive year, the Unified Lower Eagle River Chain of Lakes Commission has continued its management of aquatic invasive species, namely Eurasian water milfoil (EWM), on the lower Eagle River Chain of Lakes.
The Unified Lower Eagle River Chain of Lakes Commission (ULERCLC) successfully applied for a WDNR AIS Control Grant in August of 2011 to continue management of EWM. The grant amount was $90,508. It represents a 50% cost share, with the local municipalities and private sector (individual lake associations) funding the balance. A financial bridge loan was obtained to achieve appropriate cash flow for the project. The Commission did not need to apply for a grant for 2013 as there were funds remaining from the 2011 grant.
Last year 40.2 acres of EWM were treated. This year there was an increase in EWM, and 106 acres were treated. The fact that we saw an increase in EWM demonstrates that EWM can never be totally eliminated but only controlled.
Treatment occurred over several days during late May and early June.
Last summer native plant surveys were conducted on all our Chain lakes. Results indicated the native aquatic plant community of the lower Eagle River Chain of Lakes is of exceptional quality, and if anything, is of higher quality at present than in 2005/2006 before herbicide treatments began.
All treatment areas are monitored using protocol developed by the WDNR. Onterra, LLC, the lake management consulting firm hired by the Unified Lower Eagle River Chain of Lakes Commission conducts professional surveys. A core group of volunteers trained by Onterra monitors the lakes for existing and new aquatic invasive species, while the Onterra staff completes the professional surveys. Areas identified by the volunteers are surveyed by Onterra, and Onterra visits all marked locations and all areas previously identified. Treatment areas are monitored before and after treatments on an ongoing, year to year, basis. Spring surveys are conducted prior to treatment and the data gathered is used to refine treatment areas.
Treatment did not occur on all Chain lakes this year. Cranberry, Catfish, Eagle, Voyageur, Scattering Rice, Yellow Birch and Watersmeet were treated.
Riparians living within 150 feet of the treatment areas received written notification prior to treatment. Signs were posted at all boat landings. Schmidt’s Aquatic Plant Control, a State licensed and WDNR approved applicator, applied the herbicide, Sculpin G.
