48-acre lake near Grant County. The lake tops out around 20 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 the data behind the map says about each species, season by season:
The drawn water covers 48 acres wrapped in 1.4 miles of bank. With a 1.5 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 82% of this chart. End to end it runs roughly 0.7 mi, about 0.2 mi across. It sits in Grant County. If the bite dies, Burke Lake is 0 mi to the south.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Even in summer they hold at 5 to 20 ft; winter keeps them in 4 to 20 ft. Put Break off the point first on the milk run — a drop-off near 11 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
