Restoring The Health Of Lake Eugenia

Blue-green algae blooms have become a growing concern for Lake Eugenia. After commissioning scientific research to uncover the root cause, Friends of Lake Eugenia, with the support of LEPOA, is launching a fundraising campaign for an oxygenation project—a proven solution to improve water quality and fish habitat.

​

During the summer, oxygen levels drop below the thermocline, causing phosphorus to be released from the lakebed and fueling algae growth. The proposed system will inject oxygen into the deeper waters, which will bind to the phosphorus and restore the lake’s natural balance.

​

Following an RFP process, we selected GZA GeoEnvironmental for both their successful track record with similar projects and custom approach tailored to Lake Eugenia’s unique conditions. We are happy to report that all necessary regulatory approvals are in place and now it's up to us!

​

We’re now raising funds for the project’s next phase—a detailed customization assessment, expected to cost between $450,000 and $700,000, with implementation planned for May 2026, pending funding by December 2025.

Together, we can protect and restore Lake Eugenia for generations to come.

This all began from the extensive research from Hutchinson Environmental, who found that the algal blooms in Lake Eugenia appear to be caused by an excessive phosphorus load in the deeper areas of the lake. This is a result of over a century's worth of phosphorus accumulation in the lake's sediment,  that has been intensified from the increase in warmer temperatures and shorter ice seasons.​
