Union Lake Sarah meeting discusses zebra mussels and copper sulfate treatment plans

Concerns over zebra mussels and blue-green algae dominated discussions at the recent Polk County Board meeting, highlighting ongoing environmental challenges in local lakes. A key focus was the Union Lake Sarah meeting, where officials addressed the current cease and desist order preventing pumping unless water temperatures drop below 45 degrees. This restriction aims to protect the ecosystem while managing invasive species.

Board members revealed plans for a new survey of the lakes scheduled for July, which will help assess the extent of blue-green algae and snail infestations. One member proposed using copper sulfate as a potential solution, noting its effectiveness against both issues. However, before any application can proceed, a thorough survey is necessary to confirm the type of algae present. The estimated cost for treatment is significant, with each application projected to reach around $10,000, requiring multiple treatments annually.

In addition to environmental concerns, the board also announced upcoming district meetings, with the next one set for June 5 in Roseau County and another on October 30 in Pennington County. These gatherings will provide further opportunities for community engagement and discussion on pressing local issues. The board's proactive approach underscores the importance of addressing environmental challenges while balancing fiscal responsibilities.
