Lower Rose Canyon, located in Pima County, Arizona, is a state-regulated dam under the jurisdiction of the Arizona Department of Water Resources. Built in 1958, this gravity dam stands at a height of 41 feet and serves primarily as a Fish and Wildlife Pond. With a storage capacity of 145 acre-feet and a surface area of 7.3 acres, the dam plays a crucial role in fire protection, stock watering, and recreational activities in the area.

The dam's spillway, with a width of 34 feet, is uncontrolled, and it has a low hazard potential with a moderate risk assessment rating. Despite not being rated for its condition, the dam is inspected every five years to ensure its structural integrity and safety. The surrounding Sycamore Creek provides water to the dam, which has a drainage area of 0.78 square miles and a maximum discharge of 728 cubic feet per second.

Lower Rose Canyon Dam offers a picturesque setting for water resource and climate enthusiasts to appreciate the intersection of human engineering with natural ecosystems. Its importance in supporting local wildlife habitats and recreational opportunities underscores the need for continued monitoring and maintenance to ensure its long-term viability in the face of changing environmental conditions.
