Clark Canyon Dam

Clark Canyon Dam is an earthfill dam located in Beaverhead County, Montana, about 20 miles (30 km) south of the county seat of Dillon. The dam impounds the waters of the Beaverhead River, creating a body of water known as Clark Canyon Reservoir. The structure was constructed in 1961-1964 by the United States Bureau of Reclamation, to hold water for downstream irrigation and for flood-control purposes.

Clark Canyon Dam has a crest length of 2,950 feet (899 m), and a maximum height of 147 feet (45 m). The dam contains 1,970,000 cubic yards (1,510,000 m³) of material. The elevation of the dam crest is 5,578 feet (1,700 m). The reservoir has a total capacity of 325,324 acre feet (401,281,000 m³), and when full has a surface area of 5,903 acres (24 km²).

Construction of the dam and reservoir required the relocation of U.S. Route 91 (rebuilt as Interstate 15) and a main line of the Union Pacific Railroad. The reservoir inundated the former site of the small community of Armstead, Montana, and the site of Camp Fortunate, where the Lewis and Clark Expedition camped from August 17 to 22, 1805 and held negotiations with the Shoshone.

Canyon Dam (California)

Canyon Dam (National ID # CA00327m also known as Lake Almanor Dam) is an embankment dam on the North Fork Feather River in northern California, 16 mi (26 km) southwest of Westwood. Located about 8 miles (13 km) southeast of Chester, the dam forms Lake Almanor, a large and shallow reservoir surrounded by the Sierra Nevada mountains.

First constructed in 1910 by the Great Western Power Company as part of the Upper North Fork Feather River Project, the dam was originally planned to be built of masonry but was later changed to an earthfill design. The dam's primary purpose was to store water for the Western Canal Company, an irrigation district in the Central Valley and a subsidiary of Great Western. The dam provided flows for a hydroelectric plant about 40 miles (64 km) downstream at the Big Bend Powerhouse, today submerged by the reservoir behind Oroville Dam. Canyon Dam was modified in 1927 and 1962 to increase its usable storage. Today the dam and reservoir, owned by Pacific Gas and Electric, supply water to the 41 megawatt Butt Valley Powerhouse and provide summer flow for six hydroelectric plants on the North Fork Feather River downstream.

Canyon Dam (Texas)

The Canyon Dam in Texas is a rolled-earth dam on the Guadalupe River in the Hill Country. The water impounded by the dam forms Canyon Lake.

Geography

The dam is located 36 miles (58 km) northeast of San Antonio and 38 miles (61 km) southwest of Austin.

The dam is 6,830 feet (2,082 m) long, across a narrow section of the Guadalupe River valley. The top of the dam is 974 feet (297 m) above sea level, or 224 feet (68 m) above the riverbed. A spillway, located south of the dam, protects the dam by releasing water when the lake level rises to 943 feet (287 m) above sea level.

The dam is located near the Balcones Escarpment. The rocky canyons to the west of the escarpment can carry more water than the riverbeds of the plains to the east; this has caused problems with flash flooding in cities and towns east of the escarpment.

History

After major floods on the Guadalupe River in 1936 and 1938, state and community leaders pressured the federal government to help control flooding of the river. Congress authorized initial funds for construction of a dam in the Rivers and Harbors Act of 1945; final construction approval came in the Flood Control Act of 1954.

Clark (mascot)

Clark is the official team mascot of Major League Baseball's Chicago Cubs. He was announced on January 13, 2014 as the first official mascot in the modern history of the Cubs franchise. He was introduced that day at the Advocate Illinois Masonic Medical Center's pediatric developmental center along with some of the Cubs' top prospects such as number one draft pick Kris Bryant and Albert Almora, Jorge Soler, Mike Olt and Eric Jokisch. Over a dozen Cubs prospects were attending the Cubs' Rookie Development Program that week. The Cubs become the 27th team in Major League Baseball to have a mascot, leaving the Los Angeles Angels, Los Angeles Dodgers and New York Yankees as the remaining franchises without mascots. According to the Cubs' press release, Clark is a response to fan demands (expressed via surveys and interviews) for more kid-friendly elements at Wrigley Field Cubs games to keep pace with games in other cities that have more to offer youth fans.

Description

He is a "young, friendly Cub" who will wear a backwards baseball cap and greet fans entering Wrigley Field, which is located at the corner of Clark Street (for which he is named) and Addison Street. North Clark Street borders the third base side of Wrigley Field. According to the Cubs, the fictional character Clark is descended from Joa, the franchise's original live Bears mascot in 1916.
