Summary

Completed in 1997, this dam stands at a height of 26 feet and has a length of 673 feet, with a storage capacity of 65 acre-feet. With a controlled spillway and a maximum discharge rate of 350 cubic feet per second, SCS-Newton Gss1 serves as a crucial infrastructure for managing water flow and reducing the risk of flooding in the area.

Managed by the Oklahoma Water Resources Board, SCS-Newton Gss1 is classified as low hazard potential with a very high risk assessment rating. Despite not being rated for condition assessment, this dam has undergone regular inspections since its completion in 1997. With a valve outlet gate and a drainage area of 533 square miles, SCS-Newton Gss1 plays a vital role in maintaining water resources and protecting the surrounding community from potential flood events. As a key structure within the Tulsa District of the USACE, this dam exemplifies the importance of proper water resource management and climate resilience in the face of changing weather patterns.

With its stone core and soil foundation, SCS-Newton Gss1 showcases the collaboration between federal agencies, private owners, and state regulators in ensuring the safety and efficiency of water infrastructure projects. As part of the flood risk reduction efforts in Washita County, Oklahoma, this dam stands as a testament to the dedication and expertise of the Natural Resources Conservation Service in designing and maintaining crucial water management structures. For water resource and climate enthusiasts, SCS-Newton Gss1 is a prime example of the intersection between engineering, environmental stewardship, and community resilience in safeguarding our water supply and mitigating the impacts of climate change.

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.
