315-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 21 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 follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Brush Lake runs 315 acres with 2.8 miles of edge. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 75% of this chart. The basin spans about 1.1 mi end to end and 0.6 mi across at its widest. You'll find it in McLean County. Closest neighbour on DepthScout: Lake Holmes, 7 mi west of here.
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 6 to 21 ft, and by winter most fish are in 6 to 21 ft. If you only fish one area, make it Break off the point: a drop-off around 16 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
