Water and conditions
Water clarity runs 7.9–11.6 feet on our readings, averaging 9.6 feet, from 79 readings. Our water temperature readings average 70°F; they do not cover the whole year, so this is not a yearly average. The coldest single reading we hold is 53°F and the warmest is 81°F; the warmest monthly average is 81°F. pH averages 7.7. These readings span 2020–2026.
What is hard here
Only 1 public ramp is on file, so the launch decides where you fish.
