Water and conditions
Our water temperature readings average 50°F; they do not cover the whole year, so this is not a yearly average. The coldest single reading we hold is 34°F and the warmest is 69°F; the warmest monthly average is 63°F. pH averages 7.8. These readings span 2016–2026.
What is hard here
Wind is the limit, not the fish: 19,619 acres of open water build a short steep chop, and there is no shelter in the middle. Winter water drops to 40°F, and the warm-water species stop feeding well before you do.
