69-acre lake near St. Louis County. The lake tops out around 26 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 69 acres wrapped in 2 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. About 61% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.8 mi end to end and 0.3 mi across at its widest. It sits in St. Louis County. If the bite dies, Eagles Nest No. Four is 1 mi to the south.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 26 ft before dropping to 8 to 26 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
