Summary

This private dam on TR Rock Creek has a height of 22 feet and a storage capacity of 59 acre-feet. The dam covers a surface area of 5 acres and has a normal storage capacity of 28 acre-feet, making it a significant water resource for the region.

With a low hazard potential, Clarence Jones Dam is not currently rated for its condition assessment. The dam is primarily used for recreational activities and is an important water supply source for the area. While the dam does not have a spillway, it plays a crucial role in managing the flow of TR Rock Creek and ensuring water availability for the surrounding communities. Overall, Clarence Jones Dam stands as a vital infrastructure for water resource management and climate resilience in Buchanan County, Missouri.

As a private dam with no state or federal regulatory oversight, Clarence Jones Dam provides a unique perspective on water resource management and infrastructure development. Its location in the Rock Island District and its association with TR Rock Creek highlight the importance of sustainable water management practices in the region. For water resource and climate enthusiasts, Clarence Jones Dam serves as a fascinating case study in the intersection of private ownership, public utility, and environmental stewardship.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
