Summary

This private-owned dam, completed in 1950, stands at 30 feet high and offers a normal storage capacity of 48 acre-feet. The lake covers an area of 8 acres and is fed by Sand Creek, making it a picturesque spot for water and climate enthusiasts to explore.

Despite its low hazard potential, Peters Lake has a poor condition assessment, indicating the need for maintenance and improvement. The dam's spillway is controlled, with a width of 1 foot, and features a valve outlet gate for water management. The risk assessment for this dam is deemed very high, with a DSAC assigned date yet to be determined, highlighting the importance of implementing risk management measures to ensure the safety and sustainability of the lake.

For those interested in water resource management and climate conservation, Peters Lake presents an opportunity to witness the intersection of human-made infrastructure and natural beauty. With its rich history and potential for recreational activities, this Oklahoma gem serves as a reminder of the importance of maintaining and safeguarding our water resources for future generations.

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.
