34-acre lake near Cody Region. The lake tops out around 45 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 36 acres wrapped in 1.2 miles of bank. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. 39% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 0.5 mi long by 0.2 mi wide at the broadest reach. It sits in Park County. Its nearest charted neighbour, Gilbert Creek Lake, is 0 mi to the north.
Spring brook trout on Lost 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, 20 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.
