Summary
This private dam stands at a height of 15 feet and has a storage capacity of 128 acre-feet. It is classified as an Earth dam with a Buttress core type, serving the local community by regulating water flow to the TR to Marmaton River.
Despite being privately owned and not regulated by the state, Elliott Lake Dam has a low hazard potential with a condition assessment of "Not Rated." The dam has not been inspected recently, but its emergency action plan status and risk assessment measures are not available. With a surface area of 16 acres and a drainage area of 110 square miles, this dam plays a crucial role in supporting irrigation activities in the region.
Water resource and climate enthusiasts may find Elliott Lake Dam's design and functionality intriguing, as it offers insights into how private entities contribute to water management in a rural setting. The dam's location in Vernon County, Missouri, and its proximity to the Tulsa District highlight its significance in local water resource management. While its hazard potential is low, ongoing monitoring and maintenance of the dam are essential to ensure its continued safe operation and water supply for irrigation purposes.

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.
