Aeration lines run into the lake from the onshore tank.

If the water from Lake Casitas smells a little better these days, you can thank the wonders of hypolimnetic aeration. That’s another way of saying deep-water aeration, a process in which oxygen is force-fed to the warm, relatively stagnant layers in a body of water, and one of these systems is now up and running in Lake Casitas.
During the summer, some customers of the Casitas Municipal Water District (CMWD) had complained of a rather rancorous odor emanating from household water. Similar complaints came from some of the households served by other providers that bought water from CMWD.
