Summary
The dam stands at a height of 23 feet and has a storage capacity of 272 acre-feet. Although the dam does not have a spillway, it is equipped with one outlet gate. The primary purpose of Portwood Gss is to provide essential water resources for firefighting, livestock, and recreational activities in the area.
Situated on the TR-Brazos River under the jurisdiction of the Tulsa District of the USACE, Portwood Gss poses a high risk level due to its outdated condition assessment and lack of emergency action plan. While the dam has not been rated for its current condition, it is essential for the relevant authorities to conduct regular inspections and implement risk management measures to ensure public safety and prevent potential hazards. With a congressman representing the area being Mac Thornberry, there is a need for increased awareness and preparedness for the potential risks associated with the dam.
Water resource and climate enthusiasts interested in Portwood Gss should be aware of the dam's role in providing crucial water supply for the local community, as well as the need for improved maintenance and risk management practices. By staying informed on the dam's condition and regulatory status, enthusiasts can contribute to promoting sustainable water resource management and resilience to climate-related challenges. It is imperative for stakeholders to work together to address any potential vulnerabilities and ensure the safety and effectiveness of Portwood Gss for future generations.

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.
