589-acre reservoir near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 11 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. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Stanley Reservoir draws 589 acres inside 4.8 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Tip to tip the water measures near 2.1 mi with a 0.7-mi widest point. The water lies in Mountrail County. The nearest mapped water is Clearwater Lake, 9 mi to the northeast.
In spring, rainbow trout run shallow here, mostly 3 to 11 ft. Summer keeps them at 3 to 11 ft, and they winter in 2 to 11 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 7 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
