Summary

The dam, completed in 1955, stands at a height of 40 feet and serves the primary purpose of water supply from the TR-CHUCKAHO CREEK. With a storage capacity of 400 acre-feet and a surface area of 7 acres, Davenport plays a crucial role in ensuring a reliable water source for the community.

Owned and regulated by the Oklahoma Water Resources Board, Davenport has a low hazard potential and a very high risk assessment ranking. Despite being ungraded in terms of condition assessment, regular inspections are conducted every 5 years to ensure its structural integrity. The dam's spillway, with a controlled design and a width of 2 feet, can handle a maximum discharge of 6600 cubic feet per second, reducing flood risks in the area.

Even though Davenport's emergency action plan and risk management measures are not specified, its presence as a key water supply infrastructure highlights the importance of proper maintenance and oversight to safeguard against potential risks. With its strategic location and significant contribution to water resource management, Davenport remains a critical asset for ensuring water security and climate resilience in the region.

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.
