Lake Pleasant and New Waddell Dam
Part of: Central Arizona Project Regulatory Storage Division
New Waddell Dam is located on the Agua Fria River about 35 miles northwest of Phoenix, Arizona, and impounds Lake Pleasant. The primary purpose of this facility is to store Colorado River water for CAP use. The dam also stores Agua Fria River runoff and provides flood protection by controlling the river flows. New Waddell Dam is located one-half mile downstream of the original Waddell Dam, which is now covered in the enlarged Lake Pleasant. The original Waddell Dam was built by the Maricopa Water District (MWD) to provide water for MWD lands on the west side of Phoenix. MWD continues to receive its water supply from Lake Pleasant.
This collection contains the results of cultural resource investigations and records of cultural resource management for the Lake Pleasant area.
