ROBERTS LAKE ASSOCIATION: Roberts Lake EWM EDR Project Phase II (2018-2020)

Purpose

Roberts Lake Association is sponsoring an AIS early detection & response project which will focus on surveying, mapping and hand-pulling Eurasian Watermillfoil in Roberts Lake, Forest County. Project activities include: 1) Conduct annual early-season AIS and peak-biomass survey; 2) Volunteer AIS monitoring and hand removal; 3) Professional EWM removal; 4) Develop annual maps and letter report. Project deliverables include: 1) EWM survey data and maps; 2) Annual letter report describing the findings of the early-season survey, peak-biomass survey, hand-pulling efforts, and guidance for continued control actions. Specific conditions for this project: Annual letter report needs Dept review and approval. WDNR Lakes Management Coordinator will be provided with an electronic (pdf or word) copy of letter reports, all maps, and all aquatic plant and GIS data.

Reports and Documents
The EWM population in Roberts Lake was found to be relatively low during the August 2015 survey and professional hand-harvesting efforts were determined to be the most appropriate method for control. Professional hand-harvesting efforts have been conducted on Roberts Lake from 2015-2020. Specific details of the activities were reported within each yearsÂ’ respective annual report. This report serves as the final deliverable for the Phase II AIS-EDR Grant which has provided funding for EWM monitoring and management from 2018-2020.
The EWM population in Roberts Lake was found to be relatively low during the August 2015 survey and professional hand-harvesting efforts were determined to be the most appropriate method for control. Professional hand-harvesting efforts were conducted in 2015-2018 (Table 1). These efforts have contributed to a sustained relatively low EWM population within Roberts Lake since detection. Specific details of the activities were reported within each yearsÂ’ respective annual report.
Milfoil genetics results collected by Onterra and analyzed by MSU for Roberts [Forest], Chute Pond [Oconto], and Mt Morris [Waushara].
