76-acre lake in Ohio. The lake tops out around 18 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. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Lake Alma runs 76 acres with 1.3 miles of edge. At index 1 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 92% of this chart. Tip to tip the water measures near 0.4 mi with a 0.3-mi widest point. Closest neighbour on DepthScout: Lake Rupert (Wellston Reservoir), 3 mi north of here.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 5 to 18 ft before dropping to 5 to 18 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
