Water and conditions
Our water temperature readings average 60°F; they do not cover the whole year, so this is not a yearly average. pH averages 8.3. These readings span 2016–2022. The latest reading is from 2022, more than three years ago: read these numbers as history, not as the water today.

Fee and opening hours are blank for all 2 places in this list: a blank means we hold no such field, not that it is free or always open, and this list may not be complete.
What is hard here
Wind is the limit, not the fish: 6,548 acres of open water build a short steep chop, and there is no shelter in the middle. Only 1 public ramp is on file, so the launch decides where you fish.
