Water and conditions
Our water temperature readings average 58°F; they do not cover the whole year, so this is not a yearly average. These readings span 2021. The latest reading is from 2021, more than three years ago: read these numbers as history, not as the water today.
What is hard here
Wind is the limit, not the fish: 8,067 acres of open water build a short steep chop, and there is no shelter in the middle.
