Summary
This earth dam stands at a height of 28 feet and has a hydraulic height of 28 feet, with a structural height of 35 feet. The dam has a length of 409 feet and a storage capacity of 116 acre-feet, serving a drainage area of 140 acres along Troublesome Creek.
The dam features an uncontrolled spillway with a width of 40 feet and a hazard potential rated as low, making it a crucial structure for managing water resources in the area. With a moderate risk assessment of 3, the dam plays a significant role in mitigating flood risks while also providing benefits for fish and wildlife habitat enhancement. Despite not having a current condition rating, Troublesome Creek Watershed Dam S- 81 remains a vital asset for the local community in Lewistown, Missouri, under the ownership and management of the local government.
Water resource and climate enthusiasts will appreciate the impact of Troublesome Creek Watershed Dam S- 81 in maintaining the ecological balance of the region and in safeguarding against potential flooding events. The dam's strategic design by USDA NRCS and its low hazard potential underscore the importance of proper infrastructure for water management. This earth dam serves as a testament to effective flood risk reduction measures and the collaborative efforts of different agencies in ensuring the safety and sustainability of water resources in 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.
