Fish |
||||
| Northern California steelhead trout Oncorhynchus mykiss |

| River lamprey Lampetra ayresi |
SC | Migrates from the upper Sacramento River into smaller perennial tributary streams to spawn in the winter and spring months. Although they spawn in clean gravels, the ammocoetes (larveae) remain buried in silt and sand of backwaters and eddies. In this habitat, these juveniles feed on algae and microbes. After staying 3-5 years in the tributaries, the young eels migrate to the Sacramento River and then out to the ocean. | Known | |
| Spring-run Chinook salmon Oncorhynchus tshawytscha |
T/FT | The spring-run enters the creek from March through July. The spring-run migrates up to the higher reaches where they spend the summer and spawn the following fall. Critical for the spring-run, are the year-round, cold, deep, and protected pools that harbor adults through the summer months, until fall and winter spawning occurs. Critical to successful spawning are cold, clean, oxygenated, silt-free gravel beds. | Known | |
