With a dam height of 30 feet and a length of 470 feet, it provides a storage capacity of 34 acre-feet for various purposes. Despite not having a spillway, the dam has a hazard potential rating of "Not Available" and a risk assessment of "High (2)", indicating the need for careful monitoring and management.
While Dunn Gss is not state-regulated, it does have state permitting and inspection requirements in place. The primary purpose of the dam is listed as "Other", with the dam type being categorized as earth with a buttress core. The dam's condition assessment is currently listed as "Not Rated", highlighting the importance of regular inspections to ensure its structural integrity and safety.
With its location in the Tulsa District, Dunn Gss plays a crucial role in water resource management in the area. As a key structure on TR-Dye Creek, it serves as a vital resource for water storage and management, making it a focal point for water resource and climate enthusiasts interested in the sustainable utilization of water resources in Texas.

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.
