Riverine Nutrient Trends in the Sacramento and San Joaquin Basins, California
Peer Reviewed Title: Riverine Nutrient Trends in the Sacramento and San Joaquin Basins, California: A Comparison to State and Regional Water Quality Policies Journal Issue: San Francisco Estuary and Watershed Science, 13(4) Author: Schlegel, Brandon, California State University, Sacramento Domagalski, Joseph L., U.S Geological Survey, California Water Science Center Publication Date: 2015 Permalink: http://escholarship.org/uc/item/4c37m6vz Keywords: Sacramento–San Joaquin River Delta, nutrients, nitrogen, phosphorus, nutrient transport, nutrient loads, agricultural drainage Local Identifier: jmie_sfews_29499 Abstract: doi: http://dx.doi.org/1015447/sfews.2015v13iss4art2 Non-point source (NPS) contaminant control strategies were initiated in California in the late 1980s under the authority of the State Porter–Cologne Act and eventually for the development of total maximum daily load (TMDL) plans, under the federal Clean Water Act. Most of the NPS TMDLs developed for California’s Central Valley (CV) region were related to pesticides, but not nutrients. Efforts to reduce pesticide loads and concentrations began in earnest around 1990. The NPS control strategies either encouraged or mandated the use of management practices (MPs). Although TMDLs were largely developed for pesticides, the resultant MPs might have affected the runoff of other potential contaminants (such as nutrients). This study evaluates the effect of agricultural NPS control strategies implemented in California’s CV before and between 1990 and 2013, on nutrients, by comparing trends in surface-water concentrations and loads. In general, use of MPs was encouraged during a “voluntary” period (1990 to 2004) and mandated during an “enforcement” period (2004 to 2013). Nutrient concentrations, loads, and trends were estimated by using a recently developed Weighted Regressions on Time, Discharge, and Season (WRTDS) model. -
Transfer of the Central Valley Project
The Transfer of the Central Valley Project by Devin Odell In the spring of 1992, after six years of below-average rainfall, the perennial struggle over California's water reached a boiling point. Each of the three major groups of water interests in the state -- farmers, cities and environmentalists -- found themselves vying with the other two. At the center of this three-way tug of war was the biggest water hose in the state, the Central Valley Project (CVP), a massive set of dams, pumps, and canals built and run by the federal government. In February, CVP managers announced they could deliver less than 25 percent of the water normally used for agriculture. Farmers on about 1 million acres of land would get no water in 1992, and the rest were cut back to between 50 and 75 percent of their usual allocations. For the first time in 52 years, the CVP had completely failed some of its irrigators.' The period of low precipitation beginning in 1987 received most of the blame for this drastic step. But the Bureau of Reclamation, the federal agency in charge of the CVP, had also been forced to limit its agricultural deliveries in favor of other water users -- most notably, the Sacramento River's winter-run Chinook salmon.2 In 1981, 20,000 winter-run Chinook,listed as 'A state task force ... report stated] "threatened" under the federal Endangered that residential, business and Species Act and "endangered" under the state's municipal users might have only act, made the journey from the Pacific Ocean to half the water they would need by the spawning grounds upriver. -

State of the River Report
Lower American River State of the River Report Water Forum 660 J Street, Suite 260 Sacramento, CA 95814 1 April 2005 Lower American River The Water Forum is a diverse group of business and agricultural leaders, citizens groups, environmentalists, water managers, and local governments in the Sacramento Region that have joined to fulfill two co-equal objectives: • Provide a reliable and safe water supply for the region’s economic health and planned development to the year 2030; and • Preserve the fishery, wildlife, recreational, and aesthetic values of the lower American River. In 2000, Water Forum members approved a comprehensive Water Forum Agreement, consisting of integrated actions necessary to provide a regional solution to potential water shortages, environmental degradation, groundwater contamination, threats to groundwater reliability, and limits to economic prosperity. The Water Forum Agreement allows the region to meet its needs in a balanced way through implementation of seven elements. The seven elements of the Water Forum Agreement are: 1) increased surface water diversions, 2) actions to meet customers’ needs while reducing diversion impacts in drier years, 3) an improved pattern of fishery flow releases from Folsom Reservoir, 4) lower American River Habitat Management Element, 5) water conservation, 6) groundwater management, and 7) the Water Forum Successor Effort (WFSE). The WFSE was created to implement the seven elements of the Water Forum Agreement over the next 30 years. Additional information can be found on the Water Forum’s web site at: www.waterforum.org.

These seven developments occupy 6,190 acres of federal land within the Eldorado National Forest and 54 acres of federal land administered by the Bureau of Land Management (BLM). The proposed The Iowa Hill Development will be located in El Dorado County and will occupy 185 acres of federal land within the Eldorado National Forest. Due to the proximity of the Chili Bar Hydroelectric Project (FERC No. 2155) under licensee Pacific Gas & Electric Company(PG&E) located immediately downstream of the Upper American Project on the South Fork American River (and also under-going re-licensing), both projects were the subject of a collaborative proceeding and settlement negotiations. The current seven developments include Loon Lake, Robbs Peak, Jones Fork, Union Valley, Jaybird, Camino, and Slab Creek/White Rock. White Rock Powerhouse discharges into the South Fork American River just upstream of Chili Bar Reservoir. In addition to generation-related facilities, the project also includes 47 recreation areas that include campgrounds, day use facilities, boat launches, trails, and a scenic overlook. The 19 signatories to the Settlement are: American Whitewater, American River Recreation Association, BLM, California Parks and Recreation, California Fish and Wildlife, California Outdoors, California Sportfishing Protection Alliance, Camp Lotus, Foothill Conservancy, Forest Service, Friends of the River, FWS, Interior, U.S. -

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
