Aquatic Vegetation Surveys
The BCWD has partnered with Emmons & Olivier Resources to complete point-intercept surveys on some of the watershed's lakes to assess vegetation quality in terms of unique and invasive species. Four lakes were surveyed in 2025, with vegetation reports available:
Unique Species
Through surveys, species that are very unique to the area have been found in lakes in the watershed. In Long Lake in particular, the presence of rare species shows a pattern of healing over the years.
Aquatic Invasive Species
One of the threats facing local waterbodies is aquatic invasive species (AIS). Unfortunately, AIS are found in some of the district’s lakes and wetlands and in the St. Croix River. Curly-leaf pondweed is present in Benz, Goggins, Pat, Plaisted, Long, South School Section, and Woodpile lakes. Eurasian watermilfoil is present in Goggins, Long, Masterman, and South School Section lakes and Sinnets Pond.
Aquatic Plant Management Policy
BCWD adopted an Aquatic Plant Management Policy at the December 10, 2025 board meeting. This policy outlines when the watershed district will get involved to manage aquatic invasive species. In general, BCWD takes a holistic approach to aquatic plant management that aims to improve water quality and environmental conditions favoring native vegetation that can compete with invasive aquatic plants.
