Summary
With a height of 25 feet and a storage capacity of 27 acre-feet, the dam serves as a vital resource for the surrounding area. Situated on the TR-Grand River, the dam has a low hazard potential and has not been rated for its condition.
Despite being privately owned, Thistlethwait Lake Dam falls outside state regulation and jurisdiction, with no state permitting, inspection, or enforcement. The dam's location in Bedford, Missouri, and its association with the Rock Island District of the US Army Corps of Engineers, make it an interesting case study for water resource and climate enthusiasts. The dam's design as an earth buttress structure showcases engineering ingenuity in harnessing water resources for multiple purposes while ensuring minimal environmental impact.
While Thistlethwait Lake Dam may not be widely known, its significance in providing essential services like fire protection and stock watering makes it a valuable asset in the region. With a focus on safety and risk management measures, the dam stands as a testament to the crucial role of water infrastructure in sustaining communities and ecosystems. For those interested in the intersection of water resources and climate adaptation, Thistlethwait Lake Dam offers a compelling case study of sustainable water management practices in action.

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.
