Rating depth structure for largemouth bass.

19-acre lake near Itasca County. The lake tops out around 14 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Crum runs 19 acres with 0.7 miles of edge. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 0.3 mi, about 0.2 mi across. The water lies in Itasca County. Closest neighbour on DepthScout: Button Box, 1 mi southeast of here.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 4 to 14 ft, wintering in 4 to 14 ft. Fall largemouth bass concentrate at Main-lake point, a prime-rated point around 8 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
