1,608-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 8 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Trenton Lake draws 1,608 acres inside 6.3 miles of shoreline. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 2.2 mi long by 1.7 mi wide at the broadest reach. The water lies in Williams County. Closest neighbour on DepthScout: Epping-Springbrook Dam, 24 mi northeast of here.
Early season walleye use the shallows, holding in 2 to 8 ft. Even in summer they hold at 2 to 8 ft; winter keeps them in 2 to 8 ft. The chart's best answer is Break off the point — drop-off, 4 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 8 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (4 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 2 to 8 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (4 ft) | Jigging rap, Jig + big minnow |
| Winter | 2 to 8 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (8 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Summer fish stay in 2 to 8 ft, and winter fish hold in 2 to 8 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.

When the water first warms, white bass slide up into 1 to 8 ft. There's no big seasonal slide here — summer means 2 to 8 ft, winter 2 to 8 ft. Start at Main-lake point. It's a point holding about 4 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a slab spoon or a small topwater (schooling fish) rigged through the warm months.

Spring puts crappie in skinny water — 2 to 8 ft is the zone. Summer fish stay in 2 to 8 ft, and winter fish hold in 2 to 8 ft. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 8 ft. Warm-month bites cluster around early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
