Cotton Lake in Mono County: How and When to Fish It

• Overview

  Cotton Lake lies in Mono County, in California. It sits in mixed forest country. Surface area runs to about 5 acres — small enough to read in one session. It is high ground by California standards. The closest town, Mammoth Lakes, is 12 miles away. Further out sit West Bishop (25 miles) and Dixon Lane-Meadow Creek (27 miles). The nearest edge is a long way off, so local rules apply throughout.

• Where to Fish on Cotton Lake

  Nothing in our records gives a depth for this one. On a natural lake the weed line and the shelf beyond it do the work. The productive water is a rod length or two out, not a hundred. Fish documented in Mono County include brook trout, rainbow trout, brown trout, owens sucker and california golden trout. Read it as a county summary, not a water-by-water list. The near bank of Cotton Lake is often the one people ignore.

• Seasonal Patterns

  Long-term averages put August at about 52°F and February near 21°F. Four clear seasons, with a proper winter at one end. Winter fishing happens on the ice here, with open water back around early June. In an average year the thaw lands around early June and the freeze near mid November. The first weeks of open water and the last are the ones to plan for. At Cotton Lake the season follows that pattern closely.

• Tackle & Baits

  Ownership and access are not documented in what we hold. Formal access is not mapped, so the last stretch is likely on foot. For the trout, small spinners and a box of nymphs cover both approaches. Local rules can differ across the county line, so check where you stand. Night access is frequently treated as a separate matter. Failing this one, try Izaak Walton Lake, 0.4 miles away.
