The Bone Lake Management District is sponsoring a 3-year AIS prevention and education project including a CBCW inspection program at the public landing supplemented with ILIDS, point intercept plant survey, AIS identification and prevention workshops; public awareness, improved information signage at the landing, and monitoring for invasive plants around Bone Lake. Deliverables include a comprehensive report with: 1) A summary of project activities including CBCW survey & monitoring results, installation of ILIDS device, report on ILIDS observations (total number of launches and potential violations), inspector/monitor training, public outreach, AIS monitoring results of any detected invasive species including knotweed with appropriate maps, report on signage; 2) Watercraft inspection report (time & number of people reached); Daily CBCW survey results and remote monitoring results entered into the DNR CBCW website SWIMS database; 3) Point intercept plant survey results; 4) Verification of workshops and/or inspector training (agendas and attendance lists); 5) Copies of project educational materials and mailings; 6)) Updated APM plan; 8) AIS related materials generated or paid for by this grant. Special conditions 1) WDNR\2019s Aquatic Plant Management in Wisconsin guidance should be followed for point-intercept survey monitoring and/or aquatic plant management plan development; 2) The sponsor shall immediately contact DNR if a new aquatic invasive species is found. This scope summarizes application details 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 AIS Coordinator. It is recommended the Grantee provide AIS Coordinator with a draft final report for comment on report adequacy prior to making final payment to any consultant. The DNR shall receive a paper and electronic copy of the final report.

Bone Lake has an area of 1667 acres, a maximum depth of 43 ft and a mean depth of 23 ft. On 7 and 10 June 2013, a number of areas totaling 31.43 acres were treated with a liquid formulation of endothall (Aquathol K) to control curly-leaf pondweed (Potamogeton crispus).
On June 7, 2013 seven beds totaling 30.46 acres of the invasive species Potamogeton crispus-curly leaf pondweed (CLP) was treated with endothall (concentration of 2ppm)for purposes of CLP reduction. A comparison of the pretreatment survey frequency with the post treatment frequency shows a significant reduction in CLP in all beds. A comparison of the 2012 post treatment survey with the 2013 post treatment survey also shows a significant reduction. An analysis of the native plants resulted in a significant reduction in one native species, but it is speculated that it is not due to the herbicide application.
This Aquatic Plant Management Plan for Bone Lake, Polk County, Wisconsin presents a strategy for managing aquatic plants by protecting native plant populations, alleviating nuisance conditions, and preventing establishment of invasive species. The plan includes data about the plant community, watershed, and water quality of Bone Lake. Based on this data and public input, goals and strategies for the sound management of aquatic plants in the lake are presented. This plan will guide the Bone Lake Management District and the Wisconsin Department of Natural Resources in aquatic plant management for Bone Lake over the next five years (from 2013 through 2017)
List of Bone lake aquatic plant species and relative frequency with accompanying distribution maps for a July 2012 aquatic plant survey.
In June and July 2012, a point intercept method aquatic macrophyte survey was conducted on Bone Lake (WBIC: 2628100), in Polk County Wisconsin. Bone Lake is a 1781-acre drainage lake with a maximum depth of 43 feet. This report presents a summary and analysis of data collected in a point intercept aquatic macrophyte survey. The primary goal of the survey is to compare this PI survey with one conducted in 2007 for the long-term monitoring of aquatic plant populations and allow for the evaluation of any changes that may occur long-term.
