Designed by BUCE and Associates Inc. and Pape-Dawson Engineers, this private-owned dam serves primarily for irrigation purposes along the TR-Elm Fork Trinity River. With a height of 16 feet and a length of 985 feet, the dam has a storage capacity of 144 acre-feet, providing essential water supply for the region.
Managed by the Texas Commission on Environmental Quality (TCEQ), the dam has been inspected regularly, with the last assessment in November 2017 indicating a fair condition. The dam's spillway, with a width of 69 feet, allows for uncontrolled release of excess water to prevent overflow. Modified in 2015 for hydraulic improvements, the dam continues to play a crucial role in water management and irrigation for the area.
Although classified with a moderate risk assessment rating, the Las Colinas Reservoir No 7 Dam remains a vital infrastructure for water supply and recreation. With its strategic location and efficient design, this earth dam with buttress core types showcases the intersection of engineering excellence and environmental stewardship in sustaining water resources for the community.
