Pawnee Evaporation Ponds A, B, C are vital water resource structures located in Morgan, Colorado, specifically in the city of Brush. These ponds, completed in 1981, are owned by a public utility and fall under state jurisdiction, with regulatory oversight from the Department of Water Resources (DWR). The primary purpose of these earth dams is for evaporation, with a design that includes a hydraulic height of 11 feet and a structural height of 17 feet.

With a maximum storage capacity of 415 acre-feet and a normal storage of 230 acre-feet, Pawnee Evaporation Ponds A, B, C cover a surface area of 39 acres. The dams have a low hazard potential and were last inspected in October 2015, with a satisfactory condition assessment. Despite the high risk assessment due to their purpose, the dams are well-maintained and meet state regulatory requirements for permitting, inspection, and enforcement. The proximity of the ponds to the South Platte River further emphasizes their significance in water resource management in the region.
