Summary
Spanning across Lost Creek, this dam stands at a height of 55 feet with a structural height of 57 feet and a length of 1720 feet. With a storage capacity of 3200 acre-feet, this dam plays a vital role in providing water for irrigation and water supply in the region. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity and safety.
The dam features an uncontrolled spillway with a width of 270 feet and has outlet gates for controlled water release. The surrounding area has a surface area of 115 acres and a drainage area of 25.5 square miles. Despite its age, Lake Jacksboro Dam has undergone modifications in 1963 to enhance its hydraulic capabilities. The dam is classified as having a moderate risk level, with a hazard potential that is not currently available for assessment. With its historical significance and ongoing role in water resource management, Lake Jacksboro Dam stands as a testament to the importance of sustainable water infrastructure in the face of changing climate patterns.
Enthusiasts of water resources and climate will find Lake Jacksboro Dam to be a fascinating example of early irrigation infrastructure in Texas. Its collaboration between local government agencies, designers, and regulatory bodies showcases the complex network of stakeholders involved in managing water resources. With its storied past and continued relevance in providing water for agricultural purposes, Lake Jacksboro Dam serves as a reminder of the critical role that dams play in sustaining communities and ecosystems in a changing climate.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
