34-acre lake in Carbon County, Montana. The lake tops out around 120 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 season-by-season read for each species follows, from the map's own numbers.
Medicine Lake maps at 38 acres behind 1.6 miles of shoreline — one island included. With a 1.8 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 13% of this chart. Call it 0.4 mi long by 0.3 mi wide at the broadest reach. It sits in Carbon County. Dewey Lake sits 1 mi southeast — the closest neighbouring chart.
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 10 to 35 ft; cold water stacks them in 10 to 40 ft. Main-lake point is the standout, a point at roughly 12 ft, rated prime for fall cutthroat trout. Plan around early morning and the evening in the warm months. A trolled spoon (small) or an inline spinner covers the summer program.
