Upper Washita River Ws Scs Site 24 Dam Reservoir Report

Last Updated: December 6, 2025

Upper Washita River WS SCS Site 24 Dam, located in Hemphill, Texas, was completed in 1961 by the USDA NRCS with the primary purpose of flood risk reduction along TR-Gageby Creek.

Summary

This earth dam stands at a height of 41 feet and spans 1325 feet, providing a storage capacity of 1225 acre-feet. Despite its vital role in mitigating flood risks in the area, the dam lacks a spillway and has not been assessed for condition or hazard potential.

The dam, managed by local government authorities, falls under the regulatory jurisdiction of the Texas Commission on Environmental Quality (TCEQ) with state permitting, inspection, and enforcement in place. With a drainage area of 6.1 square miles and a normal storage capacity of 198 acre-feet, this structure plays a crucial role in managing water resources in the region. However, the dam's high risk assessment rating calls for the implementation of effective risk management measures to ensure the safety and functionality of the dam for both flood control and water resource management.

Although the Upper Washita River WS SCS Site 24 Dam plays a significant role in flood risk reduction in the region, its lack of spillway and outdated condition assessment raise concerns about its long-term effectiveness and safety. With high risk potential attributed to the dam, it is imperative for local authorities and regulatory agencies to prioritize regular inspections, maintenance, and potential upgrades to ensure the continued protection of downstream communities and water resources in the area.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
