Keswick Reservoir, on the Sacramento River near Redding, receives both water and contaminants via outflow from an upstream dam. Information is needed on dilution rates and how these vary with hydrological/meteorological forcing and reservoir management.

Beneficial re-use of sediment to fill subsided areas and restore elevations that support marsh vegetation at White Slough Unit.

Methods of addressing problems of subsidence and increasing carbon storage at White Slough include: 1] reuse of sediment to fill subsided areas and restore elevations that support marsh vegetation (left), and 2] breaching historic dikes in order to restore tidal hydrology (right).

The Mojave River is the largest of the streams and rivers that flow through southwestern San Bernardino County, CA. It extends more than 100 miles east from its source in the San Bernardino Mountains to the end east of Afton Canyon. This 3D animation takes the viewer on a tour of the entire length of the river.

The Clear Lake Hitch was formerly highly abundant and a staple food for the Pomo tribes of the Clear Lake region. The original abundance of this fish species is unknown but is believed to have declined 100-fold.
