Summary
This Earth dam, with a height of 31 feet and a storage capacity of 50 acre-feet, serves the community for recreational purposes as well. Situated on the TR-ISUM Creek, the dam has a drainage area of 25 square miles and a surface area of 3 acres, making it a vital resource for water management in the region.
Despite being privately owned, Bequette Dam - Noname 262 has a high hazard potential, indicating the need for regular inspection and maintenance. The dam, with a structural height of 31 feet, is not currently rated for its condition, and its last inspection dates back to 1978. With no state jurisdiction or regulation, the responsibility for ensuring the safety and upkeep of the dam lies with the private owner. While the dam serves multiple purposes, including fire protection and recreational activities, its importance in water resource management cannot be understated, especially in the event of emergencies or flooding risks.
With its unique design and purpose, Bequette Dam - Noname 262 stands as a critical infrastructure for water resource and climate enthusiasts to study and understand. Its location in Jefferson County, Missouri, highlights the significance of such structures in managing water flow and providing essential services to the community. As a privately owned dam, its maintenance and safety measures are crucial to prevent any potential hazards and ensure the continued availability of water resources for various purposes in the region.

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.
