Barnum Park Lake, located in Denver, Colorado, is a crucial water resource managed by the local government for flood risk reduction and recreational purposes. Built in 1956, this Earth dam stands at a height of 32 feet and spans a length of 1020 feet, with a storage capacity of 105 acre-feet. The lake sits on Weir Gulch, with a drainage area of 8 square miles and a maximum discharge rate of 2810 cubic feet per second.

Despite its low hazard potential and high risk assessment rating, Barnum Park Lake's condition assessment remains unrated, with the last inspection conducted in 1998 on a biennial basis. The Emergency Action Plan (EAP) for the dam was last revised in 1993, highlighting the need for updated emergency preparedness measures. While the lake does not have a spillway, its strategic location and vital role in flood risk management make it a significant asset for water resource and climate enthusiasts in the region.
