Summary
The dam is an Earth type structure with a height of 22 feet and a hydraulic height of 20 feet, providing a maximum storage capacity of 282 acre-feet and a normal storage of 84 acre-feet. Despite its low hazard potential, the dam has a very high risk assessment rating, indicating the need for vigilant monitoring and maintenance.
This dam, owned by the state of Oklahoma and regulated by OWRB, features a controlled spillway and one outlet valve. It spans a length of 1010 feet and covers a surface area of 21 acres. With a maximum discharge capacity of 600 cubic feet per second, the dam serves as a crucial infrastructure for managing water resources and mitigating flood risks in the region. Although it has not been inspected since 1980, the dam is in a not-rated condition and has an inspection frequency of 5 years, emphasizing the importance of regular assessments to ensure its structural integrity and safety.
As a key component of the flood risk reduction strategy in Alfalfa County, SCS-Lambert Creek Site-1 plays a vital role in protecting local communities and infrastructure from potential water-related disasters. With its historical significance and ongoing operational importance, this dam serves as a testament to the collaborative efforts between government agencies and designers to safeguard the region against the impacts of climate change and water resource management challenges.

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.
