Tadlock Hill Dam Reservoir Report
Last Updated: December 5, 2025
Tadlock Hill Dam, located in Montague, Texas, was completed in 1973 by USDA NRCS and serves as a crucial structure for flood risk reduction along the TR-WILCAWALLA CREEK.

Summary
The earth dam stands at a height of 27 feet, with a structural height of 30 feet and a length of 550 feet. It has a storage capacity of 103 acre-feet, with a normal storage level of 93 acre-feet, providing essential protection to the surrounding area from potential flooding events.
Although Tadlock Hill Dam does not have a spillway, it is equipped with one outlet gate for water control. Despite its high hazard potential, the dam's condition has not been officially rated, and it lacks an Emergency Action Plan (EAP) and risk assessment guidelines. The risk of the dam is categorized as high, highlighting the importance of implementing proper risk management measures and conducting regular inspections to ensure the safety and integrity of the structure for the community and environment it serves.
With its significant role in flood risk reduction and its location within the Tulsa District, Tadlock Hill Dam stands as a testament to the ongoing efforts to manage water resources and climate challenges in Texas. As water resource and climate enthusiasts, staying informed about the condition and management of such critical infrastructure is essential in promoting sustainable water management practices and safeguarding communities against potential hazards.

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.
