45-acre reservoir near Laramie Region. The lake tops out around 15 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 39 acres wrapped in 1.2 miles of bank. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. Platte County claims this one. If the bite dies, Festo Lake is 6 mi to the north.
Early season crappie use the shallows, holding in 2 to 8 ft. Expect a summer slide to 5 to 15 ft, then a winter hold in 5 to 15 ft. Put Deep basin first on the milk run — a deep basin near 13 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
