Middle Br. Park River #6 dam
Middle Br. Park River #6
Middle Br. Park River #6, also known as Sundvor Dam, is a vital structure owned by the local government in North Dakota. Designed by USDA NRCS, this earth dam stands at a height of 49.2 feet and was completed in 1974 for the primary purpose of flood risk reduction along the Middle Branch Park River. With a storage capacity of 724.7 acre-feet and a surface area of 6.5 acres, this dam plays a crucial role in safeguarding the surrounding area from potential flooding events.
Situated in Walsh County, North Dakota, this dam is regulated by the NDSWC and undergoes state inspections, permitting, and enforcement to ensure its structural integrity and functionality. With a spillway width of 200 feet and a significant hazard potential, Middle Br. Park River #6 is a key component in managing water flow and reducing flood risks in the region. Although the dam's condition assessment is not rated, it continues to serve its purpose effectively, with a moderate risk assessment rating of 3.
Overall, Middle Br. Park River #6 stands as a testament to successful collaboration between federal and local agencies in mitigating flood risks and protecting communities along the Middle Branch Park River. As water resource and climate enthusiasts, understanding the design, purpose, and regulatory oversight of such structures is crucial in appreciating the vital role they play in maintaining water security and resilience against natural disasters.

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 Middle Br. Park River #6
Where does the data for Middle Br. Park River #6 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 Significant 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.
