Potential effects of organic carbon production on ecosystems and drinking water quality Potential effects of organic carbon production on ecosystems and drinking water quality
Restoration of tidal wetlands in the Sacramento-San Joaquin Delta (Delta) is an important component of the Ecosystem Restoration Program of the CALFED Bay-Delta Program (CALFED). CALFED is a collaborative effort among state and federal agencies to restore the ecological health and improve water management of the Delta and San Francisco Bay (Bay). Tidal wetland restoration is intended to...

An introduction to the San Francisco Estuary tidal wetlands restoration series An introduction to the San Francisco Estuary tidal wetlands restoration series
Restoration of tidal wetlands may provide an important tool for improving ecological health and water management for beneficial uses of the San Francisco Estuary (hereafter “Estuary”). Given the large losses of tidal wetlands from San Francisco Bay and the Sacramento-San Joaquin Delta in the last 150 years, it seems logical to assume that restoring tidal wetlands will have benefits for a...

Relations between introduced fish and environmental conditions at large geographic scales Relations between introduced fish and environmental conditions at large geographic scales
Data collected from 20 major river basins between 1993 and 1995 as part of the US Geological Survey's (USGS) National Water-Quality Assessment (NAWQA) Program were analyzed to assess patterns in introduced and native fish species richness and abundance relative to watershed characteristics and stream physicochemistry. Sites (N = 157) were divided into three regions-northeast, southeast...

Effects of flow on the fish communities of a regulated California river: Implications for managing native fishes Effects of flow on the fish communities of a regulated California river: Implications for managing native fishes
We assessed the importance of flow regime to the success of native and non‐native fish species by analysing winter/spring seining data collected from 1987 to 1997 on the resident fish communities of the lower Tuolumne River, California. The data were analysed using regression models to predict the percentage of non‐native fish at a site. The regression models included various...

Fish communities of the Sacramento River Basin: Implications for conservation of native fishes in the Central Valley, California Fish communities of the Sacramento River Basin: Implications for conservation of native fishes in the Central Valley, California
The associations of resident fish communities with environmental variables and stream condition were evaluated at representative sites within the Sacramento River Basin, California between 1996 and 1998 using multivariate ordination techniques and by calculating six fish community metrics. In addition, the results of the current study were compared with recent studies in the San Joaquin...

Distribution of algae in the San Joaquin River, California, in relation to nutrient supply, salinity and other environmental factors Distribution of algae in the San Joaquin River, California, in relation to nutrient supply, salinity and other environmental factors
1. The taxonomic composition and biomass of the phytoplankton and the taxonomic composition of the phytobenthos of the San Joaquin River and its major tributaries were examined in relation to water chemistry, habitat and flow regime. Agricultural drainage and subsurface flow contribute to a complex gradient of salinity and nutrients in this eutrophic, 'lowland type' river. 2. Because of...
