Little Grass Valley is a captivating hydroelectric dam nestled in the scenic Plumas County, California, near the quaint town of Golden Trout Crossing. Built in 1961 by Bechtel, this Earth dam stands at an impressive height of 184 feet, with a hydraulic height of 198 feet and a structural height of 210 feet. The dam's primary purpose is hydroelectric power generation, while also serving irrigation and water supply needs in the region.

With a storage capacity of 94,660 acre-feet and a normal storage of 93,010 acre-feet, Little Grass Valley ensures a reliable water supply for the surrounding area. The dam's controlled spillway, with a width of 80 feet, helps manage potential high-hazard risks associated with the dam. Despite its very high risk assessment, the dam has not undergone a recent condition assessment. However, the Federal Energy Regulatory Commission oversees inspections to ensure the safety and integrity of the structure.

Surrounded by the beauty of the South Fork Feather River and boasting a surface area of 1630 acres, Little Grass Valley is a vital component of California's water resource infrastructure. Its role in providing clean energy and essential water resources underscores the importance of sustainable management practices for water and climate enthusiasts in the region.
