New Hogan Lake, reservoir in Calaveras County, California, United States

New Hogan Lake is a reservoir on the Calaveras River in the Sierra Nevada foothills of Calaveras County, about 30 miles northeast of Stockton. Its 210-foot earth-fill dam, completed in 1963, holds back 317,000 acre-feet of water, with the North and South forks of the river joining just upstream. The shoreline is irregular, with inlets, peninsulas and low islands, and a straight embankment crosses the water near the dam.

The reservoir was built in the 1960s through the construction of a dam for water storage purposes. The project was part of regional efforts to support water supply and agricultural needs.

The lake is accessible year-round with several entry points for visitors, including picnic areas and boat launches. Easy trails and open areas accommodate different activity levels and accessibility needs.

The lake's fish carry a state-issued safe-eating advisory: the California Office of Environmental Health Hazard Assessment set limits for fish caught here after finding mercury or PCBs in some species. The reservoir also holds Central Valley steelhead and spring-run Chinook salmon, both of which have declined sharply since California's dams went up.
