Water and conditions
Water clarity runs 3–5.6 feet on our readings, averaging 4.1 feet, from 454 readings. Our water temperature readings average 66°F; they do not cover the whole year, so this is not a yearly average. The coldest single reading we hold is 41°F and the warmest is 80°F; the warmest monthly average is 72°F. pH averages 7.2. These readings span 2017–2025.
