Bathymetry, topography and orthomosaic imagery for Whiskeytown Lake, northern California, fall 2018 This portion of the data release provides bathymetric data, topographic digital surface models, and orthomosaic imagery collected in and around Whiskeytown Lake in December 2018. Types: Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service Polycyclic aromatic hydrocarbons (PAHs) and suspended sediment concentrations in the San Lorenzo River, Santa Cruz, California, USA Water from the San Lorenzo River in Santa Cruz, California, was sampled to analyze for polycyclic aromatic hydrocarbons (PAHs) and suspended sediment concentrations (SSC) during the rainy seasons from 2008 to 2019 following drought conditions. The samples were collected using a US D-95 depth-integrated water sampler deployed from a bridge-box platform beneath a pedestrian bridge For each suspended-sediment sample, the water was collected in a 1-liter Nalgene bottle attached to the sampling device. After 14 days of settling time, excess water and organic matter were removed from the bottle using wet suction from a vacuum pump, and the sand fraction was then separated from silt and clay by filtration through a 0.063...

The CZU Fire ignited in the Santa Cruz Mountains, California, on August 16, 2020. By the time of full containment on September 22, 2020, the fire had burned 350 km2 (86,510 acres) in Santa Cruz and San Mateo Counties. The U.S. Geological Survey (USGS) installed four rain gages in and near the CZU Fire burn area to measure rainfall during two post-fire wet seasons. The USGS gratefully acknowledges the cooperation of Big Basin Redwoods State Park, the Big Creek Lumber Co., the McCrary family, and Brookdale Lodge in the collection of these data.

Find the updated version here: https://doi.org/10.5066/P9MAJHNI This data release includes grain-size measurements of sediment samples collected from the substrate surface and uppermost 10 cm of sediment deposits in the Klamath estuary, northern California. Samples were collected using a BMH-60 bed-material sampler deployed from a boat, or by hand trowel from subaerial or shallow-water (less than 0.5 m water depth) regions along the estuary margins and side channels. Sediment grain size was analyzed at the U.S. Geological Survey (USGS) laboratory in Santa Cruz, Calif. Particles coarser than 2 mm were sieved using a RO-TAP sieve shaker, and particles finer than 2 mm were...
