Stevens Dam dam
Stevens Dam
Stevens Dam, located on TR-LOTTS CREEK in Harrison, Missouri, is a privately owned earth dam primarily used for grade stabilization. Completed in 1990, this dam stands at a height of 25 feet with a hydraulic height of 24 feet and a structural height of 26 feet. It spans a length of 440 feet and has a maximum storage capacity of 81 acre-feet, with a normal storage level of 39 acre-feet.
The dam's spillway, which is uncontrolled, features a width of 44 feet and has a low hazard potential. With a moderate risk assessment rating of 3, Stevens Dam has not been rated for its condition assessment and does not have an emergency action plan in place. Despite lacking state regulation and inspection, this dam serves a vital role in managing water resources and mitigating risks associated with flooding in the area.
For water resource and climate enthusiasts, Stevens Dam presents an intriguing case study of a privately owned structure designed for grade stabilization. Its location and design features, such as an earth core with stone foundations, provide valuable insights into how dams can be utilized to manage water flow and protect surrounding areas from potential hazards. As an integral part of the local water infrastructure, Stevens Dam highlights the importance of proper risk management and emergency preparedness in maintaining the safety and functionality of such critical structures.

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 Stevens Dam
Where does the data for Stevens 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 Low 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.
