10-acre lake near Inyo County. The lake tops out around 27 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Longley Lake runs 10 acres with 0.5 miles of edge. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 28% of the water is 15 ft or less as modeled, the band where the food chain lives. The water lies in Inyo County. For a second option, Constance Lake lies 20 mi northwest.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 8 to 27 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 23 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
