Summary

Completed in 1996, the dam has a height of 16 feet and a storage capacity of 320 acre-feet. Situated on an unnamed tributary of Flat Rock Creek, the dam plays a crucial role in the local water resource management, with a controlled spillway and a low hazard potential.

Managed by the Oklahoma Water Resources Board, Robert L Parker undergoes regular inspections every 5 years to ensure its structural integrity and safety. Despite being rated as "Not Rated" in terms of condition assessment, the dam is considered to have a very high risk level. The presence of a single valve outlet gate indicates a simple design for water release, with no associated locks or modification history reported.

For water resource and climate enthusiasts, Robert L Parker serves as a noteworthy example of a privately owned irrigation dam in Oklahoma. With its strategic location and hydraulic features, the dam contributes to the agricultural landscape of the region while also posing certain risk factors that warrant ongoing monitoring and management efforts. As a key component of the local water infrastructure, Robert L Parker showcases the intersection of human intervention and natural resources in the context of water management.

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.
