589-acre lake near Oakland County. The lake tops out around 56 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.
Drawn out, this is 524 acres of water rimmed by 5.6 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 45% of the water is 15 ft or less, the band where the food chain lives. Figure 1.7 mi of water from one end to the other, 1 mi at the beam. You'll find it in Oakland County.

The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 19 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
