Summary
Built in 1994 by the USDA NRCS, this dam serves as a crucial water resource structure for the area, with a storage capacity of 268 acre-feet and a drainage area of 3.26 square miles. The dam stands at a height of 28 feet and stretches 1,109 feet in length, with a spillway width of 82 feet to manage maximum discharge levels of up to 762 cubic feet per second.
Although Elton Haggard Gss1 has a low hazard potential, its risk assessment is moderate, indicating the need for ongoing risk management measures. While it has not been rated for condition assessment, the dam is currently not inspected on a regular basis. Despite this, the dam remains an important structure for water resource management in the region, playing a vital role in flood control and water supply for the surrounding area. With its location on George Creek and its critical role in water management, Elton Haggard Gss1 stands as a key piece of infrastructure in the Tulsa District of Oklahoma.
As a point of interest for water resource and climate enthusiasts, Elton Haggard Gss1 offers a glimpse into the intricacies of dam construction and maintenance. With its design by the Natural Resources Conservation Service and its operational history since 1994, this earth dam serves as a reminder of the importance of infrastructure for managing water resources in a sustainable and effective manner. The dam's presence on George Creek highlights the interconnectedness of water systems and the crucial role that such structures play in ensuring the resilience of communities in the face of changing climate conditions.

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.
