Completed in 1981, the dam stands at a height of 21 feet with a length of 652 feet, providing a storage capacity of 68 acre-feet. Situated on the TR-S Fork Chambers Creek, the dam serves multiple functions including recreation and water resource management.
Despite its age, Lanman Gss No 1 has not been rated for its condition assessment and is listed as having a high risk potential. The dam features no spillway, locks, or significant drainage area, highlighting its vulnerability in times of high discharge. With no inspection frequency or emergency action plan in place, there is a need for increased monitoring and risk management measures to ensure the safety and integrity of the structure for both water resource and climate enthusiasts in the area.
As part of the Fort Worth District, Lanman Gss No 1 falls under state jurisdiction with permitting and inspection requirements in place. The dam's primary designer, the Natural Resources Conservation Service, remains responsible for its design and construction. With the potential for significant risk and the absence of critical safety measures, there is a pressing need for enhanced oversight and management to protect the surrounding community and water resources in the event of an emergency.
