Summary

is a privately owned dam located in Harrisburg, Oklahoma, along the TR EAST MUD CREEK. Built in 1970, this Earth-type dam stands at a height of 23 feet and has a hydraulic height of 20 feet. The dam has a storage capacity of 61 acre-feet and a maximum discharge of 644 cubic feet per second. Despite being categorized as a low hazard potential structure, Daniels C.M. is considered to have a very high risk due to its condition assessment not being rated.

The dam is regulated by the Oklahoma Water Resources Board and has state jurisdiction, permitting, inspection, and enforcement in place. While the last inspection took place in September 2011 with a frequency of every 5 years, the condition assessment remains unrated. With a controlled spillway type and a single valve outlet gate, Daniels C.M. continues to serve its primary purpose as an Earth dam for water resource management in Stephens County, Oklahoma.

Although the risk assessment for Daniels C.M. is very high, the dam meets state regulatory guidelines, and emergency action plans have not been prepared or updated. With a risk management plan yet to be established, there is a need for ongoing monitoring and maintenance to ensure the safety and stability of this important water resource infrastructure. Despite its age, the dam continues to play a crucial role in water management for the local area, demonstrating the importance of proactive risk management for climate and water resource enthusiasts.

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.
