Lake McClure, Reservoir in Mariposa County, United States

Lake McClure is a reservoir in the Sierra Nevada foothills created by the New Exchequer Dam, which holds back the waters of the Merced River. The body of water spans a considerable area and provides a major water surface in the midst of California's mountainous terrain.

The original Exchequer Dam was completed in 1926, establishing a significant water storage capacity in the region. The New Exchequer Dam was added in 1967, substantially expanding the reservoir's ability to hold water.

The name honors Wilbur Fiske McClure, a California state official whose work shaped regional infrastructure and outdoor recreation development. Visitors can sense this connection while exploring the foothills, where the reservoir represents a pivotal moment in the state's engineering history.

The area offers various activities for visitors, from water recreation to hiking in the surrounding landscape. Access is readily available and the region is open year-round, though water levels may fluctuate depending on the season.

Authorities regularly monitor mercury levels in fish from the lake to ensure angler safety and food quality standards. These monitoring efforts reveal how modern management must protect water quality and sustainable fishing practices.
