Mesa Creek #2, also known as Beaver Lake or Resort Lake, is a state-owned dam located in Mesa, Colorado. Built in 1926 by designers Clyde Smith, Damon Runyon, George Jensen, and Hank Koopman, this earth dam stands at a height of 15 feet and has a length of 350 feet. Its primary purpose is for recreation, offering a serene surface area of 7 acres for visitors to enjoy.

With a normal storage capacity of 49 acre-feet and a maximum storage of 77 acre-feet, Mesa Creek #2 serves as a low hazard potential structure with a moderate risk assessment rating. Although not rated for its condition as of the last assessment in 2001, the dam has undergone multiple structural modifications in 1952, 1968, and 1999 to ensure its safety and functionality. In case of emergencies, the dam is equipped with a slide (sluice gate) outlet gate to manage water flow.

Managed by the Colorado Department of Water Resources (DWR), Mesa Creek #2 is regularly inspected every 6 years to maintain its operational integrity. Despite its age, the dam continues to provide recreational opportunities for locals and visitors alike, showcasing the importance of responsible water resource management in the face of changing climate conditions.
