Summary
The earth dam, standing at a height of 50 feet, was completed in 1950 and has a storage capacity of 9,000 acre-feet. With a surface area of 293 acres and a drainage area of 10.8 square miles, the lake provides a reliable source of water for various purposes, including domestic, agricultural, and industrial use.
The dam's spillway, a controlled type with a width of 4 feet, ensures the safe release of water during periods of high discharge. While the lake's condition is assessed as fair and its hazard potential is rated as significant, the risk assessment indicates a very high risk level. Regular inspections and maintenance are conducted to ensure the dam's structural integrity and the safety of surrounding areas. Mannford Lake is a crucial component of the local water infrastructure, playing a key role in water management and supply for the region.
Managed by the Tulsa District of the US Army Corps of Engineers, Mannford Lake stands as a testament to human ingenuity in harnessing and utilizing water resources for the benefit of society. Its strategic location near the tributary of Little Salt Creek underscores its importance in the local water system. As climate change continues to impact water resources, the preservation and maintenance of reservoirs like Mannford Lake become increasingly critical in ensuring water security for future generations.

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.
