Abstract: 

Potential barriers to fish migration include any obstacles that prevent a fish from being able to swim further upstream. Natural barriers to upstream migration in Sonoma Valley are generally comprised of steep waterfalls, bedrock features that occur at elevations in the range of 660 to 1650 ft (200 to 500 m) or higher, and provide a natural upstream limit to the extent of usable habitat for anadromous fish. Man-made barriers are typically created where roads, dams or other infrastructure cross stream or creek channels.

Full barriers eliminate habitat for both spawning and rearing purposes. Estimated habitat losses amount to approximately 25% of available freshwater habitat in the Sonoma Creek watershed. See Appendix J of the Sonoma Creek Watershed Limiting Factors Analysis for details of habitat loss.
