BONE LAKE MANAGEMENT DISTRICT: Bone Lake AIS Curlyleaf Pondweed Control Project


The Bone Lake Management District is sponsoring a project to implement approved activities from the Bone Lake Aquatic Plant Management Plan. Approved activities include chemically treating curlyleaf pondweed in a limited number of high-density areas, pre/post treatment aquatic plant surveys,and turion monitoring. Deliverables include GIS maps of areas monitored; aquatic plant and turion survey results (spreadsheets and narrative summary); and a management/treatment summary. Special Condition: WDNR\2019s pre/post treatment monitoring guideline should be followed. This scope summarizes the project detail provided in the application and does not negate tasks/deliverables described therein. Data, records, and reports, including GIS-based maps and digital images, must be submitted to the Department in a format specified by the regional Lake Coordinator.

Draft: Bone Lake [2628400], Polk County, Dipotassium Salt of Endothall Herbicide Concentration Monitoring Summary, 2014
On May 28 and 29, 2014 eight beds of Potamogeton cripus (curly leaf pondweed‐CLP) totaling 30.43 acres were treated with endothall at a target concentration of 2 ppm. The treatment was found to be effective at reducing the CLP growth that was quantified before treatment, based upon frequency. The frequency from before treatment to after treatment declined 63.6%. Compared to the 2013 post treatment frequency, the 2014 increased slightly from 9.3% in 2013 to 11.3% in 2014. The pretreatment frequency from 2013 decreased in 2014, from 87% in 2013 to 74.6% in 2014, demonstrating a potential long‐term CLP reduction. The native species analysis showed a reduction in the frequency of one species (Potamogeton robbinsii) that was significant. There was an increase in frequency in 9 native species. This supports no adverse effect of the herbicide on native species. A turion density analysis showed a reduction in the mean turion density in all beds from 2013 to 2014. Beds 2‐5 showed a reduction in mean turion density for the fourth straight year. The update in non-treated CLP bed maps was not possible as the CLP never grew close to the surface to allow viewing from the surface.
