Beaver Lake may refer to:
Beaver Lake is a man-made reservoir in the Ozark Mountains of Northwest Arkansas and is formed by a dam across the White River. Beaver Lake has some 487 miles (784 km) of natural shoreline. With towering limestone bluffs, natural caves, and a wide variety of trees and flowering shrubs, it is a popular tourist destination. Beaver Lake is the source of drinking water in Northwest Arkansas, which is managed, treated and sold by Beaver Water District.
Beaver Dam was authorized by the Flood Control Act of 1944 and other following acts. The United States Army Corps of Engineers constructed Beaver Dam during the years 1960-1966, impounding a major part of the White River and creating Beaver Lake and flooding much of the valley including the remains of the historic resort town Monte Ne. The dam is located 9 miles (14 km) northwest of Eureka Springs, Arkansas. Construction of the powerhouse and switch yard began in 1963. Power generation began in May 1965 and continues today. The initial cost of the project was $60 million. The lake is approximately 50 miles (80 km) in length and covers approximately 31,700 acres (128 km2), with about 483 miles (777 km) of shoreline and an elevation of 1,120 feet (341 m). This is also the first dam in the tailwater chain to provide cold water fishery along the White River.
Beaver Lake is a 79 acre (0.3 km²) lake completely within the city limits of Sammamish, Washington. The Beaver Lake watershed is 1,043 acres (4.2 km²); the mean depth is 21 feet (6.4 m), and the maximum depth is 50 feet (15 m). Beaver Lake is actually a chain of one main and two smaller lakes, with the main lake getting the bulk of the recreation focus.
Beaver Lake is part of a chain of three lakes: Long Lake, Beaver Lake, and a third unnamed lake, 4 miles (6.4 km) East of Lake Sammamish. It is drained by Laughing Jacobs Creek, a tributary of Lake Sammamish.
There is public access via Beaver Lake Park, located at the southwest corner of the lake. Boaters are not allowed to use gasoline motors, but fishing is still a popular recreational activity on the lake. The boat launch site is not located within the Park, but rather via a WDFD water access site.
