17-acre lake near Sheridan Region. 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. What the data behind the map says about each species, season by season:
Shoreline on the chart totals 0.8 miles. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 33% of this chart, as modeled. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. It sits in Sheridan County. Coney Lake sits 1 mi west — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 8 to 26 ft, then a winter hold in 3 to 20 ft. Start at Deep basin. It's a deep basin holding about 22 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
