Lake Eugenia Water Remediation Project

LEPOA and Friends of Lake Eugenia have kicked off the fundraising campaign for the oxygenation project with two information sessions. On this page you will find:

  • The presentation used at the meetings

  • Recordings of both sessions. They were similar and both are just over 90 minutes long.

  • Six scientific papers giving background on the oxygenation system and case studies from previous projects. Each pdf has a summary page at the beginning to help you wade through the details.

Donation requests are going out from the road association reps to all members.

 

Here is the presentation shown at the two information sessions. (Click image to view.)

The presentations are the same, slightly different questions at the end.

Scientific articles providing background on the proposed oxygenation method

This article, co-authored by Dr. Kortmann, cites case studies that have successfully used aeration/oxygenation to improve lake water quality. It is a comprehensive guide to controlling toxic algae blooms.Of interest is that two of the other authors were part of the Lake Eugenia RFP process, Mark Mobley and Paul Gantzer. Mr. Mobley encouraged the installation but did not have schedule availability until 2027. Dr. Ganzer's OST system was quoted by Canada Algae Control. This quote, at $850K, was out of our budget. The Speiss cone option referenced in the article was also quoted during the RFP process but was rejected based on cost and lack of direct-scientific background of the supplier.

This is technically-detailed article that was published in the scientific journal, Lakes and Reservoir Management after being peer-reviewed. The focus of the remediation was to decrease toxic blue green algae blooms in this drinking water reservoir.

This article is a peer-reviewed publication that is specific to Lake Eugenia that scientifically supports the aeration/oxygenation approach that is being implemented. Lake and Reservoir Management is a respected international technical journal.

This article is a comprehensive evaluation of toxic blue green algae in reservoirs, written by Dr. Kortmann.  Of particular note are the 8 case studies published on article pages 82-89. On page 90 it is concluded Reservoir management approaches can help to reduce or avoid  Cyanobacteria blooms and improve raw water quality.

This article provides insight into the development of the system we are going to use in Lake Eugenia. The site-specific installations will overlap with some of the other articles presented.

This article was published by Dr. Kortmann in September 2025 that scientifically summarizes 30 years of actual installations to improve water quality in reservoirs.

It is a technical article that addresses many forms of water-quality improvement, including hypolimnic oxygenation. It also has useful information on watershed management that is applicable to Lake Eugenia. Of particular interest are the article pages 41-42
