October 19, 2017 (Lakeside) -- Lake Jennings – the lake, not the campground -- will be closed to all activities, including fishing and boating, from October 30 to November 16 so Helix Water District can study the lake’s hydraulics.
Helix is working with Scripps Institution of Oceanography to conduct the testing. The goal is to gather data to support development of a computer model that can be used to predict the lake’s hydraulic mixing actions. The data and computer model will assist Helix in future studies.
Scripps will use a dye approved by the U.S. Environmental Protection Agency as part of the testing process, and it may be possible during testing to see a slight color in the lake water that can range from pink to red. The dye is not harmful and will dissipate over the course of the testing period.
Activities not allowed during testing include use of the lake for Helix’s drinking water supply, as taking water from the lake for treatment could influence its hydraulics.
