986-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. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Belcourt Lake runs 986 acres with 5 miles of edge. 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. The shallow band under 15 ft claims about 76% of the surface — that's where the groceries are. Tip to tip the water measures near 1.8 mi with a 1.1-mi widest point. You'll find it in Rolette County. The nearest mapped water is Martin Lake, 3 mi to the southeast.
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 Deep basin first on the milk run — a deep basin near 23 ft that grades prime for winter. 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.
