The Russian River, meandering through Mendocino and Sonoma Counties, provides a diverse fishery available to anglers throughout the year.

During the cooler months when water levels are sufficient, steelhead is the primary attraction. However, drought conditions and other environmental factors in recent years have significantly affected their numbers, and now the fishery is a sliver of what is once was. Still, a few fish start entering the river after the initial heavy rainfalls in the fall or early winter, and continue throughout the colder months. It's essential to note that all Russian River salmon and steelhead are subject to catch-and-release regulations, unless they are hatchery-born and marked. Being familiar with the latest regulations is crucial both for conserving the fishery and avoiding substantial penalties.

Both smallmouth and largemouth bass are also prevalent, particularly in the middle to lower stretches of the river, becoming more active during the warmer seasons. Catfish are found in the lower reaches, preferring the slowest-moving pockets and holes. The lower sections might also surprise anglers with an occasional shad or striper.

The CDFW stocks the eastern branch with rainbow trout several times during the winter.

A significant concern for the ecosystem is the presence of pikeminnows. These aggressive fish prey on smaller species, notably the salmon and steelhead. As a result, it's beneficial for the overall health of the river to refrain from releasing them if caught.
