Summary

Completed in 1975, this Earth-type dam stands at a height of 21 feet and has a storage capacity of 135 acre-feet, primarily serving the purpose of irrigation. Situated on TR-Sassafras Creek in Burney Cemetery, the dam is regulated by the Oklahoma Water Resources Board and is subject to state inspections and enforcement.

Despite its low hazard potential, Roberts No 1 poses a very high risk due to its condition assessment being not rated. The dam features a controlled spillway and a single outlet valve. The Fort Worth District of the US Army Corps of Engineers oversees the dam's operations, with the last inspection conducted in August 2006. Although it has not been modified in recent years, the dam's risk management measures and emergency action plans are not currently up to date.

Water resource and climate enthusiasts may find Roberts No 1 intriguing for its historical significance in providing irrigation water to the surrounding area. The dam's location in a rural cemetery adds to its unique charm, while the risk assessment highlights the importance of ongoing maintenance and emergency preparedness for aging infrastructure like Roberts No 1. With its combination of practical utility and potential risks, this dam serves as a reminder of the delicate balance between water resource management and environmental stewardship.

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.
