Water and conditions
Water clarity runs 14.5–18.7 feet on our readings, averaging 16.6 feet, from 56 readings. Our water temperature readings average 67°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 2 public ramps are on file, so the launch decides where you fish.
