Summary
Completed in 1986 for flood risk reduction purposes, this earth core dam stands at a height of 27 feet and has a storage capacity of 137 acre-feet. With a low hazard potential and a very high risk assessment rating, this structure is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in November 2010.
Situated in Woods County, Lott & Sutter dam plays a crucial role in protecting the surrounding area from potential flooding events. Owned privately and maintained for the primary purpose of flood risk reduction, this structure features a controlled spillway and a single valve outlet gate. Despite its relatively low hazard potential, the dam is categorized as having a very high risk due to its location and storage capacity. The risk assessment highlights the importance of ongoing monitoring and management to ensure the safety and integrity of the dam.
With a drainage area of 1.1 square miles and a maximum discharge capacity of 1441 cubic feet per second, Lott & Sutter demonstrates the significant impact of water resource management in mitigating flood risks. Its presence underscores the importance of infrastructure like dams in safeguarding communities and ecosystems from the impacts of extreme weather events and climate change. By adhering to regulatory standards and conducting regular inspections, this dam serves as a vital component of the region's water resource and climate resilience efforts.

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.
