Small Dam dam
Small Dam
Located in Clark, Missouri, the Small Dam serves as a vital structure for grade stabilization along the TR-N. Wyaconda river. Built in 2006 by the USDA NRCS, this private-owned Earth dam stands at a height of 26 feet with a hydraulic height of 24 feet. With a storage capacity of 62.5 acre-feet and a normal storage of 41.3 acre-feet, this dam covers a surface area of 5 acres and drains an area of 150 acres.
Despite its low hazard potential, the Small Dam plays a crucial role in managing water flow and reducing erosion in the region. The dam's uncontrolled spillway and outlet gates ensure controlled discharge rates, with a maximum discharge of 13.6 cubic feet per second. While the dam has not been rated for condition assessment, its moderate risk level highlights the importance of regular monitoring and maintenance to ensure its continued effectiveness in protecting the surrounding area.
In the event of an emergency, the Small Dam's risk management measures and emergency action plan (EAP) readiness are unspecified, calling for potential improvements in preparedness protocols. As water resource and climate enthusiasts, understanding the significance of structures like the Small Dam in sustainable water management and conservation efforts is essential for safeguarding our natural resources and communities against potential risks and hazards.

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 Small Dam
Where does the data for Small 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.
