West Park, also known as Shaw Butte Detention Dam, is a crucial water resource infrastructure located in Maricopa, Arizona. Constructed in 1974, this earth dam stands at a height of 25 feet, with a hydraulic height of 25 feet and a structural height of 38 feet. Its primary purpose is flood risk reduction, serving as a vital protective measure for the surrounding area against potential flooding from the Cave Creek - TR river or stream.

Managed by the Arizona Department of Water Resources, West Park has a storage capacity of 187 acre-feet and a drainage area of 0.54 square miles. With a spillway width of 115 feet and a maximum discharge of 4980 cubic feet per second, the dam has a high hazard potential but is currently assessed to be in satisfactory condition. Regular inspections are conducted, with the last assessment taking place in March 2018.

Despite its moderate risk assessment, West Park plays a crucial role in safeguarding the city of Phoenix and its residents from potential flood events. With its strategic location and effective flood risk reduction measures, this dam stands as a testament to the proactive approach taken by the local government in ensuring water resource management and climate resilience in the region.
