Water and conditions
Water clarity runs 8–21 feet on our readings, averaging 14.7 feet, from 108 readings. Our water temperature readings average 72°F; they do not cover the whole year, so this is not a yearly average. These readings span 2017–2019. The latest reading is from 2019, more than three years ago: read these numbers as history, not as the water today.
What is hard here
Only 1 public ramp is on file, so the launch decides where you fish.
