Lower Granite Lock and Dam is a concrete gravity run-of-the-river dam in southeastern Washington in the United States. On the lower Snake River , it bridges Whitman and Garfield counties. [ 6 ] Opened 50 years ago in 1975, [ 1 ] [ 7 ] [ 8 ] the dam is located 22 miles (35 km) south of Colfax and 35 miles (56 km) north of Pomeroy .
When the dam was built, it was designed to hold 976,000 acre-feet (1,204,000 dam 3) with a surface area of 11,450 acres (4,630 ha). [2] The dam is 1400 feet wide and 340 feet high. It is a concrete structure with approximately 9 miles of earth fill wing dams and dikes supporting its surrounding areas.
It was a crucial step in construction of Hoover Dam, which could not have been built without the states' assent. The compact stands as a landmark in the development of Los Angeles, San Diego ...
But most of these dams were built between the 1930s and 1960s, and some are now beyond their useful lives. Today, we understand dams compromise entire ecosystems. We have better ways to reap the ...
In 1912 (113 years ago) () a 72 ft (22 m) multiple arch dam was constructed about 300 ft (91 m) downstream of the old dam and increased the lake capacity to 73,000 acre-feet (90,000 dam 3). The original granite dam still remains, usually under about 20 feet of water. A highway bridge (SR 18) was built over the arches of the new dam in 1923.
The removal of the four dams, which were built without tribes’ consent between 1912 and the 1960s, has cleared the way for California to return more than 2,800 acres of ancestral land to the ...
