Little Rock Reservoir is located in Los Angeles County, California, set against the backdrop of the Angeles National Forest. This 126-acre reservoir was constructed in 1924 and is situated along Little Rock Creek, a tributary of the Mojave River.

Physical Characteristics: - Surface area: 126 acres - Storage capacity: 4,600 acre-feet - Dam height: 124 feet - Fed by runoff from the San Gabriel Mountains and snowpack during winter months

Recreation and Access: The reservoir and surrounding Littlerock Recreation Area offer opportunities for boating and fishing, with rainbow trout being a target species for anglers. The area supports various outdoor activities including: - Boating - Fishing - Picnicking - Hiking - Horseback riding - Camping

The reservoir serves multiple purposes beyond recreation, functioning as a water supply source and flood control facility for surrounding communities including Palmdale and Lancaster. While the California Aqueduct now handles primary water distribution, Little Rock Reservoir remains an important backup storage system.

Natural Setting: The area features diverse wildlife and is surrounded by the majestic Angeles National Forest. The Southern California climate allows for year-round outdoor activities, though winter brings additional recreational opportunities with skiing available at nearby Mount Waterman.

Management: The reservoir is managed by the California Department of Water Resources and undergoes regular dam safety inspections. The most recent condition assessment in September 2017 rated the dam as satisfactory, with an emergency action plan last updated in February 2020.

Historical Significance: The reservoir and Littlerock Dam originally played a vital role in providing water for local farming communities. Today, while its primary water distribution role has diminished, it remains an important part of the regional landscape and continues to support local agricultural activities, including irrigation for crops such as grapes, almonds, and pistachios.
