To View the 2019 Sites Project Authority Annual Report
Sites Project Authority Annual Report 2019 Bringing resiliency, reliability, and flexibility to California's water supply We understand how critical it is to have a water system that provides multiple benefits. Sites Reservoir will produce significant benefits to the environment and secure water supply resiliency across the state for future generations. Letter from the Sites Board Chair On behalf of the Sites Project Authority (Authority), I am pleased to publish this inaugural annual report to highlight the significant progress we have made in developing Sites Reservoir. Since 2010, the Authority, representing 28 public agencies throughout California, has advanced this important project. The Authority’s strength lies in our participants, which represent the local counties where the project is located, along with cities, and water and irrigation districts throughout the Sacramento Valley, San Joaquin Valley, Bay Area, and Southern California. Through this spirit of teamwork and regional collaboration, the Authority has made great progress in advancing Sites Reservoir. In 2019, the Authority focused on project permitting, operation modeling, financial analysis, and conducting a proactive stakeholder engagement effort. We have been diligently working on developing a project that meets the needs of our participants and is affordable for our investors. We remain steadfast in our commitment to working in partnership with both landowners and project stakeholders to advance a project that meets the needs of our communities and the environment. I believe strongly that Sites Reservoir offers a unique and generational opportunity to construct a multi-benefit water storage project that helps restore flexibility, reliability, and resiliency to our statewide water supply, and provide a dedicated supply of water for environmental purposes. -
A. INTRODUCTION the Devil's Basin Research Natural Area (DBRNA
A. INTRODUCTION The Devil's Basin Research Natural Area (DBRNA) lies within the Corning Ranger District, Mendocino National Forest (Maps 1 and 2). The California black oak (Quercus kelloggii1)stands and surrounding areas of Devil's Basin were first reconnoitered in 1984 (Henry 1984), and subsequently proposed as a representative of the California Black Oak Woodland type (Holland 1986). An ecological survey of the basin was completed in 1987 (Newton 1987). Unless otherwise noted, information contained in this Establishment Record is based on this ecological survey. The DBRNA has had no history of intensive use such as logging or grazing. The DBRNA is entirely under public ownership with the Mendocino National Forest. 1) Land Management Planning The establishment of Devil's Basin RNA is recommended and evaluated in the Mendocino National Forest Land and Resource Management Plan (LRMP 1995) and the Environmental Impact Statement and Appendices for the LRMP (U.S.D.A. Forest Service 1995a-c). The land allocation for the Devil's Basin RNA was decided by the signing of the Record of Decision (ROD) for the LRMP by the Regional Forester (1995). The establishment of the DBRNA is completed upon signature of this Establishment Record with concurrence of the Station Director. The area lies within the Research Natural Areas Management Area #5 allocated to Management Prescription #11 which emphasizes the preservation of natural conditions and the protection of features for which the RNA was established (Appendix 3). B. OBJECTIVES The primary purpose for establishment of the DBRNA is to preserve a representative of a Black Oak Woodland ecosystem and its associates in a condition minimally modified by humans within the North Coast Physiographic Province for their scientific value and educational importance. -

Seeking an Understanding of the Groundwater Aquifer Systems in the Northern Sacramento Valley
SEEKING AN UNDERSTANDING OF THE GROUNDWATER AQUIFER SYSTEMS IN THE NORTHERN SACRAMENTO VALLEY Allan Fulton1, Toccoy Dudley2, Kelly Staton2, Debbie Spangler2 SOUND CONCEPT OR MISCONCEPTION To many people, the Sacramento Valley appears as an expansive groundwater basin filled with freshwater. It is also common to conceptualize the groundwater basin as an underground lake or a series of underground rivers that provide water to wells. Are these sound concepts or misconceptions? Recent interpretation of over 150 down-hole electrical resistivity logs from widely scattered locations throughout much of the northern Sacramento Valley has revealed that these simplistic concepts are incorrect. This pamphlet provides a glimpse of ongoing studies of the aquifer systems in the northern Sacramento Valley. The findings are preliminary and will likely improve as further information is gathered. Comprehensive reports of these studies should be available later in 2004. KNOWLEDGE GAPS AND NEW INVESTIGATIONS Concepts are easily formed and rationalized and can appear to be factual without sufficient field research to validate them. Until recently, only three regional investigations of the aquifer systems in the Sacramento Valley had been completed in the past 80 years and none were conducted since the mid 1970’s. Since 1997, the California Department of Water Resources, Northern District, Groundwater Section, headquartered in Red Bluff, California, has been conducting new investigations into the saline and freshwater aquifer systems in the northern Sacramento Valley. Findings from their investigations offer a greater understanding of the geology and hydrogeology in the northern Sacramento Valley. METHODS USED IN RECENT GROUNDWATER INVESTIGATIONS Geologic cross-sections have been and are currently being developed to help understand the sub-surface hydrogeology of the northern Sacramento Valley. -

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%. -

Red Bluff Diversion Dam Final EIS/EIR
Appendix B Fishery Resources APPENDIX B Fishery Resources Affected Environment The fishery resources in the Sacramento River near the Red Bluff Diversion Dam (RBDD) consist of a diverse assemblage of fish species including native and non-native (introduced species). 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 -
