Lower San Saba River Ws Scs Site 4 Dam Reservoir Report
Last Updated: December 5, 2025
The Lower San Saba River WS SCS Site 4 Dam, located in San Saba, Texas, was completed in 1958 by the USDA NRCS to primarily serve as a flood risk reduction structure along the TR-Richland Springs Creek.

Summary
This earth dam stands at a height of 28 feet and stretches 2500 feet in length, with a storage capacity of 2319 acre-feet and a drainage area of 5.8 square miles. The dam features an uncontrolled spillway with a width of 250 feet and four uncontrolled outlet gates.
Despite being last inspected in 1980, this dam is regulated and inspected by the Texas Commission on Environmental Quality (TCEQ) and is part of the flood risk reduction infrastructure in the area. With a moderate risk rating of 3, the condition assessment of the dam is currently not rated, and there is no available information on emergency action plans or risk management measures. The dam's hazard potential is not specified, but it continues to serve its purpose in mitigating flood risks in the region, under the ownership of the local government in Hall, Texas.
Water resource and climate enthusiasts may find the Lower San Saba River WS SCS Site 4 Dam an interesting case study in flood risk reduction infrastructure. Its design by the USDA NRCS, regulatory oversight by the TCEQ, and strategic location along the TR-Richland Springs Creek demonstrate a commitment to managing water resources in Texas. As efforts to address climate change intensify, understanding the role of structures like these dams in safeguarding communities from flooding becomes increasingly crucial for sustainable water management practices in the region.

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.
