Stieven Dam dam
Stieven Dam
Stieven Dam, located in Warren, Missouri, is a privately owned earth dam with a height of 43.5 feet and a hydraulic height of 42 feet. 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.

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.
- 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.
- 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.
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, environmental 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.

About Stieven Dam
Where does the data for Stieven Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
