Hot Creek

California·Eastern Sierra·37.66° N, 118.82° W

Electrofishing surveys have estimated over 11,000 trout per mile in Hot Creek's public section -- a density that would sound made up if it weren't documented by CDFW. The creek is fed by seven springs, both hot and cold, maintaining water temperatures between 55 and 60 degrees year-round, and the resulting insect production is staggering. Rainbows averaging 10-16 inches with some past 20 feed in crystal-clear water about eight miles east of Mammoth Lakes. The catch is that these are among the most selective trout in California, educated by years of catch-and-release pressure and an endless buffet of naturals that makes your size 18 BWO just one option in a river of thousands.

The public fishing section is approximately one mile long, managed by the Inyo National Forest. No wading is permitted -- you fish from the bank, which means you need to be able to cast accurately and land a fly on a specific feeding lane from 30-40 feet. Leaders of 12 feet or longer tapered to 6X-7X are standard. PMDs, BWOs, and caddis overlap from June through August, creating complex multi-hatch scenarios where figuring out what the fish are actually eating is half the challenge. Spring BWOs in April-May draw fewer anglers, and September-October brings active pre-spawn browns to the deeper runs.

Most of Hot Creek flows through the private Hot Creek Ranch, so the free public section gets concentrated pressure, especially on summer weekends. Arrive early. Mammoth Lakes is 15 minutes away with abundant lodging and three fly shops that can put you on the current hatch. The geothermal hot springs area downstream is genuinely dangerous and closed to all access -- respect the signs. If you're the kind of angler who enjoys solving puzzles more than catching numbers, Hot Creek is one of the most rewarding miles of water in the state.
