The fry-equivalent rotary trap juvenile production index (JPI) was the highest value reported in the last five years; estimated at 1,477,529 with the lower and upper 90% confidence intervals (CI) extending from 824,706 to 2,130,352 juveniles, respectively. The estimated egg-to-fry (ETF) survival rate, based on the BY2018 winter Chinook fry-equivalent JPI was 26.6%, slightly above the 21-year average ETF survival rate of 25.0%.

Table B-1 provides a species list of those fish that may likely be found at or near RBDD at some time during their life history. Of those species shown in Table B-1, four groups of fish species will be discussed together in this section because of their family relationship, life history characteristics, legal status, and occurrence within the project area. These groups include: • Native anadromous salmonids (NAS) • Other native anadromous fish (NAO) • Non-native anadromous fish (NNA) • Resident native and non-native fish (RN and RNN) TABLE B-1 Fish Found in the Sacramento River near RBDD Common Name Scientific Name Group Native Introduced Chinook salmona Oncorhynchus tshawytscha NASb X Steelheadc Oncorhynchus mykiss irideus NAS X Sockeye salmon Oncorhynchus nerka NNASd Xe Pink salmon Oncorhynchus gorbuscha NNAS Xf Pacific lamprey Lampetra tridentata NAOg X River lamprey Lampetra ayresi NAO X Green sturgeon Acipenser medirostris NAO X White sturgeon Acipenser transmontanus NAO X Striped bass Morone saxatilis NNAh X American shad Alosa sapidissima NNA X Rainbow trouti Oncorhynchus mykiss RNj X Hitch Lavinia exilicauda RN X Sacramento splittail Pogonichthys macrolepidotus RN X Hardhead Mylopharodon conocephalus RN X Sacramento pikeminnow Ptychocheilus grandis RN X Speckled dace

Taylor Anadromous Fisheries Branch ABSTRACT This report covers the 22nd annual (1974) inventory of king salmon (Oncorhynchus tshawytscha) spawning populations in the Sacramento-San Joaquin River system. It is a compilation of estimates of fall- and spring-run king salmon spawning populations for every stream in the Sacramento-San Joaquin system which supports a significant spawning run, and partial counts of late fall- and winter-run king salmon. Estimates are made from counts of carcasses and live fish on spawning areas, aerial redd counts, and counts of fish migrating past Red Bluff Diversion Dam. The estimated 1974 escapement of fall-spawning (fall- plus spring-run) king salmon in the Central Valley is 244,054 fish. This figure is 8% of the historic (1953-1973) average of 301,000, and is down 14% from the 1973 estimate of 283,000. Appendix Tables present fall- and spring-run spawning escapements by stream for 1974, and by major streams for the years 19.64 through 1974.

  • Chapter 4-Overview of Analytical Approach
    CHAPTER 4 OVERVIEW OF ANALYTICAL APPROACH This chapter describes the scope and extent of the environmental analyses for this EIR/EIS, presented by study area region (see Section 2.1). Specifically, this chapter describes the framework for the impact analyses, identifies the environmental resource areas evaluated in this EIR/EIS, and explains why some resource areas have been dismissed from further evaluation. In addition, this chapter introduces the approach for the cumulative effects analysis, discusses irreversible and irretrievable commitments of resources, and discusses the relationship between short-term uses of the environment and maintenance and enhancement of the long-term productivity of resources. 4.1 EVALUATED ENVIRONMENTAL RESOURCE AREAS Environmental resources within the project study area were examined to determine whether they could be directly or indirectly affected by implementation of a project that changes water management on the lower Yuba River. Some, but not all, of these environmental resources include: (1) fisheries and aquatic resources; (2) rivers used to convey transfer water, including conveyance of transfer water stored in Oroville and Shasta reservoirs; (3) rivers that may be influenced by implementation of the Proposed Project/Action or alternatives; (4) the Yuba Groundwater Basin and overlying lands within Yuba County; and (5) lands within YCWA and its Member Unit service areas. The environmental resource areas evaluated in this EIR/EIS, by region and Export Service Area, are presented in Table 4-1. Table

It is a compilation of estimates of fall- and spring-run salmon spawning populations for every stream in the Sacramento-San Joaquin system which supports a significant spawning run, and partial counts of late-fall- and winter-run salmon.
