Summary
This privately owned earth dam, completed in 1965, boasts a height of 20 feet and a storage capacity of 130 acre-feet, serving as a crucial component in the management of Rock Creek. Despite its low hazard potential, Solliday Al is subject to regular state inspections and enforcement to ensure its structural integrity and operational efficiency.
With a spillway width of 1 foot and a controlled spillway type, Solliday Al is equipped to handle a maximum discharge of 5100 cubic feet per second, further highlighting its importance in flood mitigation efforts. The dam's primary purpose is classified as 'Other', indicating its multifaceted role in water resource management. Additionally, its risk assessment ranks at a very high level (1), underscoring the need for continuous monitoring and risk management measures to safeguard the surrounding community and ecosystem.
As part of the Tulsa District and under the regulatory oversight of the OWRB, Solliday Al plays a pivotal role in ensuring water security and climate resilience in the region. Its strategic location in Hectorville, Okmulgee, Oklahoma, underscores the interconnectedness of water resources, infrastructure, and climate considerations. As water resource and climate enthusiasts continue to advocate for sustainable practices, Solliday Al stands as a beacon of responsible dam management and environmental stewardship in the face of evolving climate challenges.

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.
