King #3, also known as Twin Lakes #1, is a private dam located in Mesa, Colorado, with a primary purpose of recreation. Built in 1940, this earth dam stands at a height of 30 feet and has a length of 443 feet, providing a storage capacity of 91 acre-feet. The dam overlooks the North East Creek-TR river or stream, and is regulated by the Colorado Division of Water Resources.

Despite its low hazard potential and fair condition assessment, King #3 poses a high risk due to its location and design. With a maximum discharge of 3800 cubic feet per second, the dam's spillway, although not specified, has a width of 110 feet. The dam's outlet gates consist of slide (sluice gate) and uncontrolled mechanisms, and it has undergone inspections every 6 years, with the last assessment completed in September 2016.

For water resource and climate enthusiasts, King #3 offers a glimpse into the intricate world of dam infrastructure and regulation. Its blend of historical significance, recreational purpose, and risk factors make it a compelling case study in the management of water resources and the importance of maintaining critical infrastructure for the safety and enjoyment of communities.
