Chauncey Anderson

Welcome to the Staff Profile for Chauncey Anderson, Hydrologist and Water Quality Specialist at USGS Oregon Water Science Center in Portland, Oregon.


Chauncey Anderson is a Hydrologist and Water Quality Specialist for the USGS Oregon Water Science Center (ORWSC), where he has worked since 1991. He studies the effects of land and water management on aquatic resources; primarily water quality, sediment, and ecosystem responses, in Oregon and nationally. He has worked extensively around the hydrologic impacts of reservoir operations. In 2009-2013, he was Co-Chair of the Water Quality Subteam for the Secretarial Determination on the Klamath Hydroelectric Settlement Agreement, and currently works on other Klamath Basin issues. Since 2000 he has also studied hydrologic and water quality effects on amphibians as part of USGS's Amphibian Research and Monitoring Initiative, or ARMI.  He is the author of the USGS' national protocol on measurement of turbidity in water, which led him to work on the use of turbidity and other continuously measured surrogates to estimate real-time concentrations of suspended sediment and other constituents in water.
