Pena Blanca, located in Santa Cruz, Arizona, is a state-regulated dam managed by the Arizona Department of Water Resources. Built in 1958, this rockfill dam stands at a height of 60 feet and serves primarily as a fish and wildlife pond, with additional purposes including recreation. The dam has a storage capacity of 1,240 acre-feet and covers a surface area of 45 acres, drawing water from the Pena Blanca Creek.

Despite being classified as having a high hazard potential, Pena Blanca is currently in fair condition as of its last assessment in March 2018. With a moderate risk assessment rating, the dam undergoes inspections regularly, with the most recent one conducted in March 2021. While no emergency action plan (EAP) information is provided, the dam's spillway type is uncontrolled, with a width of 40 feet to manage potential excess water discharge.

Pena Blanca's presence not only supports local wildlife and recreational activities but also plays a crucial role in managing water resources in the region. As an essential part of the state's infrastructure, the dam's maintenance, inspections, and regulatory oversight ensure the safety and sustainability of its operations for the benefit of both the environment and the community.
