486-acre lake near Ohio. The lake tops out around 60 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. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 479 acres of water rimmed by 8.5 miles of bank. An index of 2.8 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 20% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 2.6 mi end to end and 0.8 mi across at its widest. The nearest mapped water is Woodhull Lake, 8 mi to the northwest.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Spring brook trout concentrate at Main-lake point, a prime-rated point around 15 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (15 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (36 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 10 to 25 ft. Shallow bay flat is the standout, a feeding flat at roughly 6 ft, rated prime for summer brown bullhead. Time it for after dark and the evening.
