During November 2018, the Camp Fire burned more than 150,000 acres in Butte County, California. The fire was the deadliest and most destructive in California history, destroying more than 18,000 structures and causing at least 85 fatalities. The U.S. Geological Survey sampled surface water in areas affected by the Camp Fire, plus an unburned control site, during two post-fire sampling events, January 21-23, 2019 and February 28 - March 1, 2019. During each of those two sampling events, surface-water samples were collected at 8 stream locations. These 16 water samples were filtered using filters with multiple pore sizes (1.2 µm, 0.8 µm, 0.45 µm, and 0.22 µm) to evaluate colloid transport of trace elements. The filtrates...

The Cache Creek Settling Basin (CCSB) is a 13.3 km2 levee-bounded sediment retention basin located at the modern terminus of Cache Creek near the eastern boundary of Yolo County, approximately two miles NE of Woodland, California. The Cache Creek Settling Basin was constructed in 1937 by the U.S. Army Corps of Engineers to trap suspended sediment from the upper Cache Creek watershed during high-flow events, with the purpose of preserving the floodway capacity of the Yolo Bypass, a larger leveed floodway located downstream. This dataset includes subsamples from sediment cores and shallow streambank sediment collected from the Sacramento River watershed. Sediment cores were collected in the Cache Creek Settling Basin...

This dataset includes data for in-situ solid materials and suspended sediments from surface-water samples, as well as surface-water chemistry from samples collected during storm events at Malakoff Diggins State Historic Park, Nevada County, California. In-situ solid samples were collected during 2015 along six vertical transects along the cliff walls of the mine pit. Surface-water samples were collected during 2014 and 2016 from Hiller Tunnel and from drainage networks below the in-situ sampling sites during runoff conditions. In-situ and suspended-sediment samples were analyzed for grain-size distribution, X-ray diffraction (XRD) for quantitative mineralogy, inductively coupled plasma - mass spectrometry (ICP-MS)...
