ramps for both angling and other watersports. Theodore Roosevelt Lake Theodore Roosevelt Dam and the Roosevelt Lake it forms are considered perhaps the crowning achievements of SRP. With the initial funds raised by the association in 1903, an ambitious project was begun several miles east of Phoenix in the Tonto Valley, at the confluence of the Tonto Creek and the Salt River. At its completion in 1911, Roosevelt Dam was the tallest masonry dam in the world at 280 feet (85 m). It was dedicated by U.S. President Theodore Roosevelt, for whom the dam and the reservoir are named. In 1996, a massive expansion project aimed at increasing the capacity of the lake was finished. The dam was resurfaced with concrete and raised an additional 77 feet (23 m), which had the effect of increasing the lake's capacity by over 20%, and providing much needed flood control space on the Salt River. Shortly after completion, however, the area entered into a prolonged period of drought, and it would be some time before the new capacity was used, with the lake finally reaching historic levels of 90% capacity in early 2005. With an at-capacity surface area of nearly , Roosevelt is the largest lake that is wholly inside the state of Arizona. It can store of water at capacity. Apache Lake Apache Lake was formed by the construction of the Horse Mesa Dam, finished in 1927. Several miles downstream from Roosevelt, the dam stands high. The lake itself is considerably smaller than Roosevelt at only of surface area at full capacity, and can store of water. Like the rest of the Salt River lakes downstream from Roosevelt, Apache Lake is long and narrow, filling the bottom of the canyon it resides in. It does have a hydroelectric generating station. Canyon Lake Canyon Lake, the third lake on the Salt River, is created by the Mormon Flat Dam. The dam was completed in 1925, being the second of the dams to be completed. The dam is named for a nearby geographical feature, a flat campground where Mormon pioneers from Utah would often stop on their journey to the Phoenix area. Downstream from Apache Lake, it is considerably smaller with only of surface area when full, holding . Like the other Salt River dams, it is equipped with hydroelectric generators. Saguaro Lake Saguaro Lake is formed by the Stewart Mountain Dam, downstream from
