New Waddell Dam, Embankment dam in Maricopa County, Arizona, United States
New Waddell Dam is an embankment dam on the Agua Fria River in Arizona that creates Lake Pleasant, a large water reservoir. The structure holds water that serves the central and southern parts of the state.
Construction of this dam took place from 1985 to 1994 and replaced an older structure dating from 1927 that now sits underwater. The new project was built to increase the water storage capacity of the region.
The dam forms part of the Central Arizona Project, delivering Colorado River water to users throughout central and southern Arizona for agricultural and urban needs.
Access to the lake and its activities happens through Lake Pleasant Regional Park located near the dam. Visitors should know that water levels and availability of recreation options can change depending on the season and weather conditions.
The structure has two large spillways that together can handle enormous water flows if needed for safety. These overflow mechanisms are crucial for protecting infrastructure downstream from flooding.
