Set in Sierra County, Onion Valley Reservoir is a California water. The bank is 6,283 feet above sea level. Head to East Quincy, 9.8 miles away, for anything you forgot. Chico is the closest city, 51 miles away. Within a short drive: Duck Soup Pond near enough 2.4 miles, Delahunty Lake 2.9 miles, Fowler Lake near enough 6.8 miles, Little Grass Valley Reservoir 7.4 miles and Eureka Lake near enough 9.1 miles. A county line runs close by, so local bylaws can differ within a short drive.
Depth is unmeasured here, so let the shoreline guide you. Levels move with the draw rather than the rain on water like this. Built water gives depth close in, which suits a bank angler. Survey and observation records for Sierra County include rainbow trout, brook trout and brown trout. The list covers the county rather than this water alone, so treat it as a guide. At Onion Valley Reservoir light and wind decide more than tackle does.
The year swings from about 32°F in January to roughly 62°F in August. Temperature moves within a narrow band, and so does the fishing. It is not guaranteed even in a cold spell, so check yourself. The cooler months are the comfortable ones to fish here. The season on Onion Valley Reservoir rarely departs from it.
We have no record of the rules that apply on this bank. No built facilities appear in mapping around this water. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry.
