23-acre lake in Carbon County, Montana. The lake tops out around 50 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. Here's the year, species by species, as the scoring engine sees it.
North Hidden Lake maps at 19 acres behind 1.2 miles of shoreline. With a 2 development index there's bank structure worth casting at, in moderation. 33% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.3 mi end to end and 0.2 mi across at its widest. It sits in Carbon County. Thiel Lake sits 1 mi southwest — the closest neighbouring chart.
Spring brook trout on North Hidden Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Break off the point — drop-off, 25 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
