Summary
It was designed by Bob Heagler and is regulated by the Dam and Reservoir Safety Program in Missouri. The dam has a high hazard potential and a satisfactory condition assessment, with a moderate risk assessment rating.
With a storage capacity of 1185 acre-feet and a drainage area of 1450 acres, Stieven Dam plays a crucial role in managing water resources in the area. The dam, situated on a tributary of Massey Creek, has a spillway width of 100 feet and a maximum discharge capacity of 3350 cubic feet per second. Despite being uncontrolled, the dam has been inspected regularly, with the last assessment conducted in May 2016.
For water resource and climate enthusiasts, Stieven Dam presents an intriguing case study in dam safety and management. As one of the key structures in the region, its risk assessment, condition evaluation, and emergency preparedness measures serve as important benchmarks for similar dams nationwide. The dam's role in flood control, water storage, and environmental protection underscores the critical importance of effective dam regulation and maintenance in ensuring the resilience of water infrastructure in the face of changing climate conditions.

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.
