The Theodore Roosevelt Lake in Arizona USA is an artificial lake , which the Salt River and Tonto Creek dammed. The reservoir and dam wall were named after Theodore Roosevelt . Its maximum depth is 74.7 m. The only town on the waterfront is Roosevelt .
The reservoir was the prerequisite for the growth of the southwestern city of Phoenix (Arizona) into a metropolis.
Dam wall
The Theodore Roosevelt Dam (Theodore Roosevelt Dam), which dams this lake, was started in 1905 and opened in 1911. It was the first of five major projects, the States after the Reclamation Act of 1902, which also the United Reclamation Service, the predecessor of the Bureau of Reclamation , was founded, were started. Their purpose was irrigation, flood control and power generation. The original height of the arch dam was 84 m and its length 216 m. Further details for the wall height are 63 m and 93 m (the differences could be due to the reference points). First the dam was called "Salt River Dam No. 1", it was not until 1959 that the dam and reservoir were officially renamed after Theodore Roosevelt.
When it was completed, the dam was 84 m high, making it the highest masonry dam in the world. It was one of the first dams of modern times, which were higher in the USA than the Kurit Dam in Persia, which was built in the Middle Ages . At the time of its creation, the reservoir is also said to have been the largest man-made lake on earth with its 2 billion m³ content.
Between 1989 and 1996 the dam wall was increased by 23 m to 109 m (other information: 107 m). The storage capacity was increased by 20% during the renovation. The cost of $ 430 million includes three other measures: the new routing of Highway 188 over a new bridge, renovations to the hydropower plant, and the Lake Tap tunnel in connection with the pressure pipes. After the renovation, there was a longer dry period, so that the storage space only reached 97% of its capacity in 2008.
The dam's hydropower plant has an electrical output of 36 MW .
