Fish

The endangered Chinook Salmon and steelhead spawn in the Napa River and in its many tributaries. The steelhead run has been reduced from historical levels of 6000 adults to a few hundred fish. Nonetheless, the river still supports a diverse population of native and non-native fish species and an active recreational fishery. We find bluegill, black bass in the upper river; and striped bass, sturgeon and many non-game species such as the endangered splittail, yellowfin goby and silversides in the lower river. Watch Napa RCD Senior Biologist, Jonathan Koehler's fascinating short video: Diversity in the Napa River to learn more about the native fish in the River.

Beaver, river otter, mink, muskrat, raccoon, deer, gray fox and bobcat also live in the riparian habitat. This article in the New Humanitarian provides some basic information about beaver and their surprising impact on the ecosystem.

Occasionally, harbor porpoise make their way up the tidal portion of the Napa River as far as downtown Napa.
