CVFPP Conservation Strategy Appendix H. Central Valley Chinook Salmon Rearing Habitat Required to Satisfy the Anadromous Fish Restoration Program Doubling Goal

California Department of Water Resources (DWR) | July 14, 2016
Summary

NewFields and Cramer Fish Sciences, in collaboration with the California Department of Water Resources FloodSAFE Environmental Stewardship and Statewide Resources Office Conservation Strategy team, applied best available tools and data to estimate the area of suitable juvenile salmonid rearing habitat required in each of the Conservation Planning Areas (CPAs) to achieve the Anadromous Fish Restoration Program (AFRP) “doubling goal” for Chinook salmon populations. The AFRP goal was used to align the Conservation Strategy objectives with existing,longstanding efforts by partner resource management agencies. Historical and existing suitable rearing habitat area for juvenile salmonids was estimated with the Estimated Annual Habitat approach that uses measured hydrology and modeled hydraulic relationships between river flow and inundation area to calculate areas of inundation with timing, duration, and frequency suitable for juvenile California Chinook salmon rearing. The rearing habitat required to support the doubling goal populations was estimated using the Emigrating Salmonid Habitat Estimation model. The details of the approach and the full range of calculated results are presented in the following sections and appendices.
