Summary
This earth dam, with a height of 19.6 feet and a hydraulic height of 14 feet, was completed in 1998 and has a storage capacity of 94 acre-feet. With a low hazard potential and a moderate risk assessment rating, Jjrp is crucial for managing water resources and protecting the surrounding area from potential flooding events.
Although not regulated by the state and lacking inspection and enforcement mechanisms, Jjrp plays a significant role in controlling the flow of Bear Creek and ensuring the safety of the community. The dam's uncontrolled spillway, with a width of 20 feet, helps in managing excess water during periods of high discharge, ultimately reducing the risk of flooding downstream. Despite not having a condition assessment rating, Jjrp's presence as a grade stabilization structure is essential for maintaining the stability of the surrounding landscape and water resources in the region.
Overall, Jjrp stands as a vital infrastructure for water resource and climate enthusiasts, serving its primary purpose of grade stabilization along Bear Creek in Missouri. With a focus on managing water flow, reducing flood risk, and ensuring the safety of the community, this earth dam continues to play a crucial role in water resource management 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.
