USGS Interdisciplinary Science Contributes to Native Fish Ecology Efforts in the Delta

With the development of the Central Valley (CVP) and State Water (SWP) projects, the natural flow of the Sacramento-San Joaquin Delta has been reengineered to provide water for California’s growing population and agricultural needs. These changes have drastically reduced natural...

Reducing Mercury Loads in The Cosumnes River

The Cosumnes River watershed has seasonal, non-point source hotspots for total mercury and methylmercury production, which discharge to the Sacramento-San Joaquin River Delta in north-central California. To reduce mercury loads to the Delta, researchers created open-water deep cells at the downstream end of wetlands.

Wildfires, Water, and CAWSC Science

California's landscape is prone to drought and warmer climates. The recent drought lasted five years (2011 – early 2017), bringing with it many environmental issues including the increased prevalence, severity, and duration of wildfires. While there used to be a distinct "wildfire season" in California, the threat of wildfire is no longer restricted to a single season.

Water Science in the Lake Tahoe Basin

Lake Tahoe currently attracts almost 3 million visitors a year. After the 1960 Winter Olympics at Squaw Valley, it became a major tourist attraction, which resulted in increased development and an influx of motorized watercraft to the lake. Damage to the lake became noticeable with a reduction in lake clarity. This catalyzed a movement to use science and regional planning to reduce human...

Harvesting Earthquake Fault Slip f­rom Laser Images of Napa's Vineyards

A new U.S. Geological Survey-led study suggests that earthquake-related deformation just below the Earth's surface can be quite different from how it is expressed at the surface.
