  • Fannie Lake (NE) Public Water Access Site — 1 lane. DNR Division of Parks and Trails.

Water and conditions

Our water temperature readings average 72°F; they do not cover the whole year, so this is not a yearly average. pH averages 7.8. These readings span 2016–2025.

What is hard here

Only 2 public ramps are on file, so the launch decides where you fish.
