BALSAM LAKE P & R DISTRICT: Balsam Lake Aquatic Invasive Species Control Project


The Balsam Lake P & R District is sponsoring a project to implement approved activities from the Balsam 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 bed mapping, purple loosestrife and giant knotweed mapping and control; and EWM monitoring at boat landings. Deliverables include GIS maps of areas monitored; aquatic plant 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.

Volunteer and compensation hours.
On 3 June 2013, two areas totaling 13.4 acres were treated with a liquid formulation of endothall (Aquathol K) at a target concentration of 1500 ug/L (1.5 mg/L) active ingredient (ai) to control curly-leaf pondweed (Potamogeton crispus). Water samples were collected from each sample site using an integrated water sampler which collects water from most of the water column. Water samples were collected at intervals of approximately 1, 2, 4, 6, 8, 24 and 48 hours after treatment (HAT) at sample sites in treatment areas. Water samples were collected at intervals of approximately 1, 3, 5, 7, 10, and 14 days after treatment (DAT) at sample sites in untreated areas. Samples were taken to shore after completion of each sample interval, and 3 drops of muriatic acid were added to each sample bottle to fix the endothall and prevent degradation. Samples were then stored in a refrigerator, until shipped to the US Army Engineer Research and Development Center (ERDC) laboratory in Gainesville, FL for analysis of endothall.
