This time of year we often are asked, "What is that smell coming from the Lake?"

During the summer, Lake Mendocino separates into layers: warm, oxygen-rich water on top and colder, denser water below. As leaves and other organic matter sink, bacteria break them down, consuming oxygen in the process. This decomposition releases gases like hydrogen sulfide (H₂S), which causes the rotten egg smell.

As fall approaches, the surface water cools, becoming denser. Eventually, it sinks, mixing with the bottom water. This is “fall turnover”! It redistributes oxygen and nutrients throughout the lake. The released gases, while smelly, are a natural byproduct of decomposition.

📢 Public Notice: Cyanobacteria (blue-green algae) have been detected in low concentrations at Lake Mendocino. Current levels do not pose a significant health risk, but as a precaution, please be aware of potential symptoms like skin irritation, nausea, vomiting, or diarrhea if you come into contact with the water. Advisory signs have been posted at water access points with guidelines.

About the test results: "Testing of the water sample showed a small amount of cyanobacteria, which can produce toxins, but the levels were very low. We also found a very small amount of one type of toxin, anatoxin, but it was at the lowest level our testing could detect." See test report for more details.
