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. -

A unique aspect of this incident was the fact that it happened during a flood scenario well within its design and operational procedures, prompting research into its causes and determining methods to prevent similar events from reoccurring. In this study, a hydroclimatic analysis of Oroville Dam’s catchment is conducted, along with a review of related design and operational manuals. The data available allows for the comparison of older flood-frequency analyses to new alternative methods proposed in this paper and relevant literature. Based on summary characteristics -

The Great New Year's Flood of 1997 in Northern California
The Great New Year's Flood of 1997 in Northern California by Maurice Roos' The New Year's flood of 1997 was probably the largest in the 90-year Northern California record which begins in 1906. It was notable in the intensity, volume of flood water, and the areal extent from the Oregon border down to the southern end of the Sierra. Many new flood records were set. This was a classic orographic event with warm moist winds from the southwest blowing over the Sierra Nevada and dumping amazing amounts of rain at the middle and high elevations, especially over a 3 day period centered on New Year's Day. The sheer volume of runoff exceeded the flood control capacity of Don Pedro Dam on the Tuolumne River and Millerton Reservoir on the upper San Joaquin River with large spills of excess water. Most of the other large dams in northern California were full or nearly full at the end of the storms. Amounts of rain at lower elevations were not unusual. For example, downtown Sacramento in the middle of the Central Valley had 3.7 inches during the week from December 26 through January 2. But Blue Canyon, at the one-mile elevation between Sacramento and Reno, had over 30 inches, an orographic ratio of over 8, far more than the usual 3 to 4 for most storms. Many Valley folks could not understand that there was a problem because they were not seeing a lot of rain. Meanwhile, the entire northern Sierra was observing 20 inches, some 40 percent of average annual precipitation. -
Chapter 7: Alternative Evaluation
Chapter 7 Alternative Evaluation The potential for water quality improvements in the Delta was evaluated in terms of the position of X2 and the resulting Delta outflows. Shifting X2 downstream improves the habitat for Delta smelt and reduces water quality stress for other species, including salmonids. X2 is a Delta management tool; it is defined as the distance in kilometers from the Golden Gate Bridge to the location where the tidally averaged near-bottom salinity in the Delta measures 2 parts per thousand (ppt). East of X2, water becomes progressively fresher, and west of X2 the water becomes more saline, until it reaches the ocean, which has a salinity of approximately 35 ppt. Habitat quality in the Delta is degraded when the salinity in the Delta increases. The highest salinities occur during the fall and early winter, when Delta outflow is at its lowest. Water quality degradation is most pronounced in Dry and Critical years. Figure 7-8 shows the change in the average X2 positions during September and October in Dry and Critical years for each of the alternatives. Alternative C performs best in terms of the shift in the location of X2 by 0.3 to 1.0 kilometer (km) seaward, followed by Alternative B and then Alternative A. Alternative D provides the least water quality benefit, with an average shift of 1 km to the east in July through August, and a 0.3 km shift in September through November. Shifting X2 requires a significant quantity of water. Releases from Sites Reservoir to improve Delta environmental water quality range from 174 TAF/yr under Alternative D up to 242 TAF/yr under Alternative C. -

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.
