San Bernardino Optimal Basin Management
The San Bernardino area of southern California has complex water-management issues. As an aid to local water managers, this report provides an integrated analysis of the surface-water and ground-water systems, documents ground-water flow and constrained optimization models, and provides seven examples using the models to better understand and manage water resources of the area. As an aid to...
Ground-Water Nitrate and Organic Carbon Inputs to the Lower San Joaquin River
This proposal addresses drinking water and aquatic habitat issues associated with nitrate and organic carbon in the lower San Joaquin River (SJR).
Analysis of Factors Causing Mercury Impairment in Water Bodies of the Sierra Nevada, California
The SWRCB has requested assistance from the USGS in analyzing the factors that control Hg concentrations in fish tissue in the Sierra Nevada. Specifically, the SWRCB wants to know whether Hg and (or) MeHg in bed sediment and (or) suspended sediment could be potentially useful in the future as a 303(d) listing criteria. The SWRCB has requested that the USGS perform an analysis of existing data for...
California Water Use, 2010
In 2010, Californians withdrew an estimated total of 38 billion gallons of water per day, compared with 46 billion gallons per day in 2005.
Iron Mountain: An Extraordinary and Extreme Environment
At its peak production, Iron Mountain ranked as the tenth largest copper production site in the world, sixth in the U.S. and first in California. During its operation, from 1879 - 1963, ten different mines throughout the site's 4,400 acres were the source of not just copper, but also silver, iron, gold, zinc and pyrite (iron sulfide). A century of active mining at Iron Mountain took an...
New Methods to Measure Reservoir Storage Capacity and Sedimentation in Loch Lomond Reservoir
A new method of measuring the storage capacity and sedimentation of Loch Lomond Reservoir, Santa Cruz shows promise to help water managers more effectively assess changes in water-storage capacity in similar basins with steep, narrow drainages in mountainous terrain. The method employs a combination of bathymetric scanning using multibeam-sidescan sonar, and topographic surveying using laser...
Sources of Microbial Contamination at Public Beaches, Santa Barbara
The focus of this study is on analysis of existing hydrologic, chemical, and microbiological data; collection of surface-water and shallow ground-water hydrologic, chemical, and microbiological data; and characterization of dissolved organic carbon composition.

El Dorado National Forest after the 2014 King Fire
El Dorado National Forest after the 2014 King FireThe 2014 King Fire burned 97,717 acres in the El Dorado National Forest and on private timberlands. The fires in these burn areas reduce the forest canopy, exposing snowpack to direct sunlight. This increases the rate of snowmelt and evaporation, impacting runoff and groundwater replenishment.
