Water and conditions
Water clarity runs 9.5–14.8 feet on our readings, averaging 11.5 feet, from 54 readings. Our water temperature readings average 71°F; they do not cover the whole year, so this is not a yearly average. pH averages 8.2. These readings span 2016–2025.
What is hard here
Only 1 public ramp is on file, so the launch decides where you fish.
