Summary
Completed in 1989, this Earth-type dam stands at a height of 26 feet and stretches 542 feet in length, holding a storage capacity of 151 acre-feet. With a low hazard potential and a moderate risk assessment rating, this dam plays a crucial role in managing water resources in the region.
Situated along the TR-Troublesome Creek, this dam is under the jurisdiction of the Rock Island District and is not regulated by the state of Missouri. Despite being unpermitted and uninspected by the state, Troublesome Creek Watershed Dam R-38 operates with a structural height of 28 feet and a spillway width of 52 feet, ensuring proper discharge during peak flow events. The dam's condition remains unrated, but its risk management measures are in place to mitigate potential threats.
As water resource and climate enthusiasts, understanding the significance of Troublesome Creek Watershed Dam R-38 in flood risk reduction efforts is crucial. With its strategic location and design, this dam serves as a key component in the overall water management system of the area, contributing to the protection of surrounding communities and ecosystems. Monitoring and maintaining the integrity of this dam is essential to ensure its continued effectiveness in safeguarding against flood events and preserving the natural balance of the Troublesome Creek watershed.

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.
