Water and conditions

Water clarity runs 14–18.4 feet on our readings, averaging 16.4 feet, from 30 readings. Our water temperature readings average 71°F; they do not cover the whole year, so this is not a yearly average. These readings span 2017–2025.

What is hard here

Only 1 public ramp is on file, so the launch decides where you fish.
