81-acre lake near Grant County. The lake tops out around 10 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Stan Coffin Lake runs 81 acres with 1.6 miles of edge. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.7 mi with a 0.3-mi widest point. The water lies in Grant County. For a second option, Quincy Lake lies 1 mi south.
In spring, channel catfish run shallow here, mostly 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Deep basin is the standout, a deep basin at roughly 10 ft, rated prime for winter channel catfish. Time it for after dark and the evening.
