282-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 7 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. Here is how the season plays out for each species, straight from the data behind the map.
Gascoyne Lake maps at 282 acres behind 2.9 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 1.2 mi long by 0.5 mi wide at the broadest reach. It sits in Bowman County. Cedar Lake sits 12 mi northeast — the closest neighbouring chart.
Start shallow in spring: yellow perch sit in 2 to 7 ft that time of year. They don't go far with the seasons — 2 to 7 ft covers summer, 2 to 7 ft covers winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 7 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 2 to 7 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
