The team will document history and provenance of mining sediment deposits in the Central Valley by granulometry, X-ray fluorescence spectroscopy, magnetism, and geochronology. It will track historical erosion of hydraulic mining sediments in the piedmont through a combination of photogrammetry, channel change analysis, and field surveys.

The research team will link spatial and temporal patterns and processes of deposition in Sutter and Yolo Bypasses (leveed floodplains of the Central Valley) with erosion of piedmont tailings of the lower Bear, Yuba, and Feather Rivers downstream of the last major dam on each. The research will track the movement of fine sediments derived from hydraulic mining tailings in the lower Sacramento Valley. Recent field evidence of episodic piedmont erosion and bypass deposition calls for a new investigation of the hydraulic mining sediment delivery problem in the lower Sacramento valley over the last century. This research employs a suite of new techniques and data to investigate the temporal and spatial links between Central Valley floodplain sedimentation and erosion of hydraulic mining sediment in the Sierra piedmont over the last century. The spatial distribution of hydraulic mining sediment reworking and deposition in flood bypasses over the last century are relevant to the fate of contaminants, flood conveyance, and the land-use in the lower Sacramento Valley of California, which is undergoing a massive program of restoration and development, and to basic research on valley floor sediment budgets and floodplain sedimentation. Hydraulic mining in the Sierra Nevada of California displaced great volumes of sediment as a byproduct of gold extraction from placer gravels. Primary Place of Performance Congressional District:

Interested in joining the conversation about how to protect your local water supplies from mismanagement or climate-induced disasters such as drought? Here are options: This dashboard provides a current and historical perspective on water issues facing the state using a variety of publicly available datasets. Meanwhile, snow water content in the central and southern Sierras broke records, while in the northern Sierras snow water content levels are second to recorded historical levels from 1983. And reservoirs storing Delta water have experienced record lows in recent years.Ĭalifornia's statewide snowpack on April 3 tied with 1952 for the highest on record for that date.

Groundwater in the San Joaquin Valley has been drained more quickly than it can be recharged, so thousands of wells have gone dry. But one good winter after years of drought does not mean California no longer faces water shortages.ĭroughts are becoming more common and more extreme as the climate crisis intensifies, and communities across the state dependent on depleted underground aquifers and parched Colorado River supplies do not have enough water to meet the demands of their farmers and cities. California has endured deluge after deluge this winter, including several atmospheric rivers that dumped tons of rain all at once.
