Jenkinson Lake is a lake located in El Dorado County, California near Pollock Pines, California named after Robert Jenkins the famous bull fighter. There are two main parts, the upper and lower lake. The lower lake is about eight times larger than the upper lake, which is to the northeast of its partner. The lower lake is more of a rounded body, while the upper is more narrow.

The Sly Park Dam can be found to the southern part of the lake, and an auxiliary dam can be found to the southeast.

Sly Park Dam is located near Pollock Pines, California in the United States. The dam impounds Sly Park Creek and Hazel Creek, natural tributaries of the North Fork Cosumnes River, to form a 41,000 acre-foot (51,000 dam3), 650-acre (260 ha) reservoir called Jenkinson Lake. It was constructed as part of the American River Division of the Central Valley Project to provide irrigation water to a portion of El Dorado County, California. The dam was begun in May 1953, with clearing operations, and was completed in mid 1955. The earthfill Sly Park Dam is 190 feet (58 m) high, with a hydraulic height of 170 feet (52 m), and 760 feet (230 m) long. Its auxiliary dam is 130 feet (40 m) high and 600 feet (180 m) long. The spillway of Sly Park Dam is actually in the auxiliary dam: it is a concrete chute 170 feet (52 m) long and can carry 6,700 cubic feet (190 m3) per second, while the outlet works at the foot of the dam can carry 47 cubic feet (1.3 m3) per second. The drainage area of Sly Park Creek behind the dam is 47 square miles (120 km2). The Camino Conduit diverts water roughly 7.2 miles (11.6 km) west from the Jenkinson Reservoir for irrigation purposes. Water is also diverted from Camp Creek into Jenkinson Lake to increase the total water yield.

Union Valley Reservoir is a reservoir in eastern El Dorado County, California, about 20 miles (32 km) northeast of Placerville. The 277,000 acre-feet (342,000,000 m3) lake is in Eldorado National Forest in the Sierra Nevada at an elevation of 4,870 feet (1,480 m). It was formed in 1963 (1963) by the 453-foot (138 m) high earth and rockfill Union Valley Dam on Silver Creek, which is a tributary of the American River. The reservoir is part of the Upper American River Project of the Sacramento Municipal Utility District, a public electric utility, which operates the dam and many other dams in the area. Recreation such as boating, fishing and camping is available there. It stores snow melt runoff during the spring and releases it during the summer when electrical demand is greatest to a chain of hydroelectric power plants downstream. Union Valley Powerhouse at the base of the dam has a capacity of 46.7 MW and is operated as a peaking power plant, supplying electricity during times of the greatest demand. Consumptive rights to the water itself are held by the City of Sacramento, California. The reservoir is fed by Big Silver Creek, Jones Fork Silver Creek, Tells Creek, Wench Creek and the outflows of Robbs Peak and Jones Fork powerhouses. Jones Fork Powerhouse is not on Jones Fork Silver Creek but instead conveys water from Ice House Reservoir. Robbs Peak Powerhouse gets its water from the Middle Fork American River headwaters, by way of Loon Lake Reservoir, and small reservoirs on Gerle Creek and South Fork Rubicon River. Downstream from Union Valley Dam, Silver Creek waters are largely diverted through two additional powerhouses below small reservoirs before joining the South Fork American River a few miles north of Pollock Pines, California. Silver Creek was an intermittent creek before the development of Union Valley Reservoir and the diversions from the Middle Fork American River.
