83,596-acre reservoir in Ohio. The lake tops out around 24 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 the data behind the map says about each species, season by season:
The drawn water covers 83,300 acres wrapped in 215.9 miles of bank. The 5.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. End to end it runs roughly 107.7 mi, about 2.1 mi across. Its nearest charted neighbour, Lamberjack Reservoir, is 10 mi to the west.
Spring largemouth bass on Wauseon Reservoir hold shallow, usually 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 7 to 24 ft. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
