Summary

Built in 1976, this Earth-type dam stands at 28 feet tall and spans 138 feet in length, with a storage capacity of 200 acre-feet. The dam serves a primary purpose of "Other" and has a low hazard potential, with a very high risk assessment rating.

Managed by the Natural Resources Conservation Service, Gwendolyn Hunsaker features a controlled spillway and a single valve outlet gate. Despite not being rated for condition assessment, the dam is inspected every five years, with the last inspection conducted in November 2001. While the risk of the dam is considered very high, it remains a vital structure in the region for water resource management and climate resilience.

Located in Caddo County, Gwendolyn Hunsaker plays a crucial role in mitigating flood risk and providing water storage for Spring Creek and its surrounding areas. With its strategic design and state-regulated operations, this dam represents a key infrastructure asset in Oklahoma's water resource management efforts. For water resource and climate enthusiasts, Gwendolyn Hunsaker serves as a fascinating case study in dam construction, regulation, and risk assessment in the face of evolving environmental challenges.

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.
