A beaver dam or beaver impoundment is a dam built by beavers; it creates a pond which protects against predators such as coyotes, wolves and bears, and holds their food during winter. These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species and ecosystem ...
Beavers continue to pile on more material until the dam slopes in a direction facing upstream. Dams can range in height from 20 cm (7.9 in) to 3 m (9.8 ft) and can stretch from 0.3 m (1 ft 0 in) to several hundred meters long. Beaver dams are more effective in trapping and slowly leaking water than man-made concrete dams.

In 2014, a review of beaver dams as stream restoration tools proposed that an ecosystem approach using riparian plants and beaver dams could accelerate repair of incised, degraded streams versus physical manipulation of streams. [61] The province of Alberta published a booklet in 2016 providing information on using beaver for stream restoration ...
The beaver dam is constructed using branches from trees the beavers cut down, as well as rocks, grass, and mud. Where naturally-occurring woody material is limiting, beavers may build their dams largely of rocks. [58] The inner bark, twigs, shoots, and leaves of such trees are also an important part of the beaver's diet. [59]
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 ...
Although Beaver Dams was not made a national park, the Historic Sites and Monuments Board was created in 1919 to develop a heritage policy at the federal level for historic sites. In 1921, soon after the Board's formation, the Board recommended the designation of the Battle of Beaver Dams site as a National Historic Site , one of its earliest ...
Beaver Dams was the original name from 1863 to about 1947 when the Arizona Department of Highways (now ADOT) used the singular name of Beaver Dam on road signs and the new name has been used since. The Mormon Road was used by Forty-niners in 1849 and Mormon colonists and other travelers from then on.
