Sediment Pond 16-1 dam
Sediment Pond 16-1
Sediment Pond 16-1 is a privately owned earth dam located in Oliver County, North Dakota, along Square Butte Creek. Designed by Keith R. Yapp, PE, the dam stands at a height of 23 feet and stretches 800 feet in length, with a storage capacity of 267 acre-feet. The dam serves a primary purpose of sediment control and is regulated by the North Dakota State Water Commission, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
With a spillway type of "Uncontrolled" and a spillway width of 75 feet, Sediment Pond 16-1 has a low hazard potential and a moderate risk assessment rating of 3. The dam features a vertical lift outlet gate and a stone core foundation, providing stability and reliability in managing water flow and storage. While the dam's condition is currently rated as "Not Rated," its moderate risk level indicates the need for ongoing monitoring and potential risk management measures to ensure its continued safety and effectiveness in sediment retention and water resource management.
Overall, Sediment Pond 16-1 plays a vital role in sediment control and water management in the region, with a focus on protecting water quality and downstream ecosystems. As a key infrastructure for environmental conservation and water resource sustainability, the dam's design, construction, and regulatory oversight underscore its importance in mitigating sediment runoff and preserving the health of Square Butte Creek and its surrounding watershed.

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 Sediment Pond 16-1
Where does the data for Sediment Pond 16-1 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.
