Goodwin, located in Knights Ferry, California, is a public utility dam on the Stanislaus River that serves multiple purposes, including flood risk reduction, irrigation, and water supply. Built in 1912, this multi-arch dam stands at a height of 101 feet and has a storage capacity of 500 acre-feet. With a drainage area of 996.5 square miles, Goodwin plays a crucial role in managing water resources in Calaveras County.

Managed by the California Department of Water Resources (DWR) under the Safety of Dams program, Goodwin is subject to regular state inspections, enforcement, and permitting to ensure its structural integrity and operational safety.

Emergency action plans are in place, with the last revision conducted in September 2020, to address any potential risks and ensure swift responses in case of emergencies.

With a historical significance dating back over a century, Goodwin continues to be a vital infrastructure for the local community in managing water resources and mitigating flood risks along the Stanislaus River.
