RICE LAKE P & R DISTRICT: Rice Lake Non-native Milfoil Survey, Planning, & Mgmt


The Rice Lake Protection and Rehabilitation District is sponsoring a response project for a recent infestation of hybrid Eurasian water milfoil in Rice Lake. Project deliverables include GIS data & maps of areas monitored, aquatic plant data and reports, AIS monitoring reports, and an updated aquatic plant management plan. Specific project activities include: 1) Whole lake point intercept plant survey; 2) SCUBA removal; 3) Herbicide treatment; 4) Professional and volunteer AIS monitoring; 5) Aquatic plant management plan update. Special Conditions: 1) WDNR\2019s Aquatic Plant Management in Wisconsin guidance shall be followed for point-intercept survey monitoring and aquatic plant management plan development. The NOR Native Plant Protection Strategy shall be integrated into the plan; 2) Sponsor shall contact DNR immediately if a new AIS is found; 3) Grant monies may not be used for control of established curly-leaf pondweed; 4) AIS monitoring volunteers shall be trained and follow Citizen Lake Monitoring Network protocols. 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 Lakes Biologist.

In early June, during a CLP bedmapping survey of Rice Lake in Barron County, two Lake Education and Planning Services (LEAPS) employees discovered what looked like Eurasian watermilfoil in Clearwater Bay off the south basin of Rice Lake (Figure 1). Samples of the suspect plants were collected and subsequently identified by aquatic plant experts and DNA testing as hybrid watermilfoil, a cross between Eurasian watermilfoil (non-native) and northern watermilfoil (native).
