1,608-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 8 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.
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.
