Mark Wilmer Pumping Plant. The CAP delivers Colorado River water, either directly or by exchange, into central and Southern Arizona.The project was envisioned to provide water to nearly one million acres (405,000 hectares) of irrigated agricultural land areas in Maricopa, Pinal, and Pima counties, as well as municipal water for several Arizona communities, including the metropolitan areas of ...
Pinal County was carved out of neighboring Maricopa County and Pima County on February 1, 1875, during the Eighth Legislature. In the August 18, 1899, issue of The Arizona Magazine, the name "Pinal" is said to come from the pine-clad Pinal Mountains. [3] Pinal County was the second-fastest-growing county in the U.S. between 2000 and 2010. [4]
The lake's design capacity was 24,500 acre-feet (30,200,000 m 3) of water, with a surface area of over 2 square miles (5.2 km 2). Over the years, siltation and vegetation have reduced the capacity and surface area, so that much of the reservoir is a shallow marsh with extensive stands of cattails and rushes.

Arizona's oldest rocks overall are metamorphosed volcanic rocks, including basalt and rhyolite and related sedimentary rocks, that now constitute the bottom of the Grand Canyon and formed beginning 1.8 billion years ago. The Verde district at Jerome, in Yavapai County also preserves rocks from this period.
Less than 1 ⁄ 2 mile (0.80 km) from the national forest boundary, the Granite Reef Diversion Dam diverts all remaining water in the Salt River into the Arizona Canal and Southern Canal, which deliver drinking and irrigation water to much of the Phoenix metropolitan area. The dam and canals are part of the Salt River Project.
Fredlake reasoned that beaver dams would raise the water table, allowing groundwater to recharge the river's flow in the dry season. From 1999 to 2002, 19 beavers were released into the SPRNCA, a 40-mile (64 km) stretch of the river, in Cochise County. By 2006 there were more than 30 dams. The beavers also dispersed widely and rapidly.
