Summary
Built in 1966, Todd serves as a vital resource for the surrounding area, with a maximum storage capacity of 120 acre-feet and a normal storage level of 80 acre-feet. The dam stands at 22 feet tall and stretches 770 feet in length, impounding the TR-CANEY RIVER to ensure a reliable water supply for the community of RAMONA.
Despite its low hazard potential, Todd is subject to state regulation and inspection by the Oklahoma Water Resources Board. The dam features a controlled spillway and a single valve outlet gate for water release, with a maximum discharge capacity of 5000 cubic feet per second. Although its condition is not currently rated, Todd's risk assessment is categorized as "Very High (1)", underscoring the importance of ongoing risk management measures to ensure the safety and functionality of this essential water infrastructure.
With its earth core and stone foundation, Todd plays a crucial role in maintaining water supply stability for the region. As a key component of the local water infrastructure, it is essential for Todd to meet regulatory guidelines and undergo regular inspections to address any potential risks and safeguard its continued operation. Todd stands as a testament to the importance of sustainable water resource management in the face of evolving climate challenges.

Dam Data Reference
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.
