520-acre lake near North Dakota. North Dakota Game & Fish survey water. 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. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Loon Lake draws 520 acres inside 3.5 miles of shoreline. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 48% of the water is 15 ft or less, the band where the food chain lives. Call it 1.4 mi long by 0.9 mi wide at the broadest reach. You'll find it in Bottineau County. Closest neighbour on DepthScout: Pelican Lake, 2 mi east of here.
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 7 to 24 ft, then a winter hold in 7 to 24 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 7 to 24 ft; cold water stacks them in 7 to 24 ft.

A drop shot (goby/minnow) or a ned rig covers the summer program.
