274-acre lake near Hamilton County. Iowa DNR survey water. The lake tops out around 12 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. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 274 acres wrapped in 2.5 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.9 mi end to end and 0.7 mi across at its widest. It sits in Hamilton County. If the bite dies, Peterson Pit West is 13 mi to the south.
Spring largemouth bass on Little Wall Lake hold shallow, usually 2 to 10 ft. They move out to 4 to 12 ft in summer and finish the year down in 4 to 12 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
