The Pinto Dam is a dam in Grant County in the US state of Washington .
The dam was built as part of a project by the United States Bureau of Reclamation ; it was completed between 1946 and 1948 as part of the huge Columbia Basin Project and is used to store water for irrigation, flood control and power generation. The Pinto Dam is an earth dam, 40 m high and 579 m long at the top. It stores the water away from a river.
The six-mile (9.6 km) long, crescent-shaped reservoir, Billy Clapp Lake, was originally called Long Lake Reservoir, but was renamed after one of the project's sponsors, an Ephrata lawyer . You can fish all year round on the lake. There are American perch , crappies , rainbow trout and glass eyes perch caught. The Stratford Wildlife Recreation Area borders the east shore of Billy Clapp Lake and provides shelter for migrating waterfowl. Another fairly large lake, Brook Lake, is located below the dam.
Columbia Basin Project
Pinto Dam and Billy Clapp Lake are part of the Main Canal (1951) within the Columbia Bsin Project. The canal is eight miles long and runs from Banks Lake to Billy Clapp Lake. From the outlet of Billy Clap Lake, the lower reaches of the Main Canal runs westwards and branches off near Adco on Washington State Route 28 into the East Low and West Canal. The total length of the canals is 34 km including 8.58 kilometers within Long Lake. By building Long Lake Dam, later renamed Pinto Dam, the Bureau of Reclamation used the river terrace to save costs.
Billy Clapp Lake
The Billy Clapp Lake created by the Pinto Dam lies along its entire length within the Long Lake Coulee. The river terrace (engl. Coulee ) is the result of the Missoula floods . The reservoir is 9.6 km long and about 800 m wide with a maximum depth of 91 meters. Before the reservoir was created, the basin it fills today contained five smaller lakes (Long Lake, Coffee Pot Lake, Pot Lake, Cold Spring Lake, and July Lake).
Pinto Dam
The Pinto Dam is a zoned dam wall that has been filled in with earth and rocks; it is about 580 m long at the crown and a total of 40 m high. An unregulated overflow channel runs on the left side of the dam through a channel carved into the rock. The Billy Clapp Head Works (dt. Front stabilizer ) has radial gates to control the discharge in the lower reaches of the Main Canal.
