Joan Lopez
Joan Lopez is a Projects Program Coordinator with the California Water Science Center (CAWSC). She answers questions regarding project proposal reviews, project reviews, the Science Program Integration Group, the California Leadership Team, and the Peer Support Worker Program.
Joan started with the California Water Science Center as a surface water Hydrologic Technician in 2012 while completing her Bachelors of Science in Geology from California State University, Sacramento. After graduating in 2015, She continued to work for the center as a Hydrologist running the sediment lab in Sacramento, CA and supporting laboratory safety activities as well as applying GIS to bathymetric surveys. She then took on the position of Projects Program Coordinator in 2019 where she continues today to support the CAWSC Projects Program and the Associate Director for Projects, while she also obtained her Associates of Science degree in Geographical Information Systems from American River College in 2020.

San Antonio Reservoir Bathymetric Survey and Sedimentation Study
Over time, the flow of water into the San Antonio Reservoir has caused the build-up of sediment, decreasing storage capacity. Since water storage is a crucial issue in California, up-to-date information on the reservoir is needed. To accomplish this, the San Francisco Public Utilities Commission approached the USGS California Water Science Center to conduct a bathymetric (depth) survey and other... - Data

Sediment transport in two tributaries to the San Joaquin River immediately below Friant Dam—Cottonwood Creek and Little Dry Creek, California
Two tributaries to the greater San Joaquin River watershed, Cottonwood and Little Dry Creeks, in California’s Central Valley, were assessed for sediment and streamflow dynamics between October 1, 2011, and September 30, 2019. The two systems deliver sediment to the San Joaquin River below Friant Dam, California. Dams create downstream discontinuities in streamflow and sediment transport and therefAuthorsDan R.W.

The San Antonio Reservoir is a large water storage facility in Alameda County, California, and is a major component of the Hetch Hetchy Regional Water System (RWS). The RWS is a water-supply system owned and operated by the San Francisco Public Utilities Commission (SFPUC) and provides water for about 2.7 million people in the San Francisco, Santa Clara, Alameda, and San Mateo Counties.
