BLACK OTTER LAKE P & R DISTRICT: Black Otter Lake AIS Control

Purpose

Black Otter Lake District proposes to continue to educate the public and manage aquatic invasive species (AIS) in Black Otter Lake. Specifically, Black Otter Lake District will: 1. Annually assess the aquatic plant community utilizing early-season and fall aquatic invasive species surveys and summer point-intercept surveys following DNR protocols. 2. Control AIS using early-season chemical treatments and hand-pulling. 3. Educate the public on AIS prevention activities utilizing the Clean Boats/Clean Waters Program, Hortonville High School students to conduct AIS surveys, use of trail-style cameras at the public launch, and installation of informational kiosks at the major access points of the lake. Volunteer AIS monitoring results will be entered into SWIMS. 4. Plant emergent plant species and conduct other habitat improvement projects in the lake. 5. Generate annual project reports with a summary of education and control activities, survey results, as well as recommendations for the following year. The project elements and deliverables are specified in the grant application materials submitted to the Department dated February 1, 2013.

Reports and Documents
To address aquatic plant management, a review of current aquatic plant conditions and management techniques is necessary to be sure that the lake is being managed in the best way possible for the resource and its users. To that end, this report outlines past management, the current conditions, and a review of best management actions moving forward.
For more than a decade, the members of the Black Otter Lake District have actively managed the aquatic invasive species Eurasian watermilfoil (Myriophyllum spicatum) (EWM) and curly-leaf pondweed (Potamogeton crispus) (CLP). Both species have dominated the lake at various times over this period. Treatments for exotic species date back to 2003. On May 27, 2014, a survey for exotic species was conducted on Black Otter Lake by Cason & AssociatesÂ’ staff. This survey was used to determine the area and location of CLP. It utilized the point-intercept aquatic plant survey map as a guide. Surface observations and rake tows were used to determine the abundance of CLP at each location.
