Summary
Built in 1965, this earth dam stands at a height of 30 feet and has a hydraulic height of 10 feet, with a length of 200 feet. The dam's primary purpose is classified as "Other," with a storage capacity of 70 acre-feet and a surface area of 4 acres. It is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state inspection, permitting, and enforcement.
The dam on TR-Horse Creek is designed with a controlled spillway and features a single valve outlet gate. Despite its low hazard potential, Dickey Glen is rated as having a very high risk due to its location and structural characteristics. The dam has not been assessed for condition, emergency action plans, or risk management measures. The risk assessment indicates a high level of concern for potential hazards associated with this structure, highlighting the importance of ongoing monitoring and maintenance to ensure the safety and integrity of the dam.
For water resource and climate enthusiasts, Dickey Glen presents an interesting case study in dam safety and risk management. Its location in a high-risk area, coupled with limited assessment and emergency preparedness measures, underscores the need for proactive monitoring and intervention to mitigate potential hazards. As a regulated structure under state jurisdiction, Dickey Glen serves as a reminder of the importance of maintaining and inspecting dams to protect communities and water resources from the risks associated with aging infrastructure and changing environmental conditions.

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.
