Solberg Dam; Dorvan dam
Solberg Dam; Dorvan
Solberg Dam, also known as Roseth Dam, is a private earth dam located in Williams County, North Dakota. Built in 1930 by designer Roger Smith, this dam serves as a Fish and Wildlife Pond with a storage capacity of 170.2 acre-feet. With a normal storage level of 47.6 acre-feet and a surface area of 16.6 acres, Solberg Dam plays a crucial role in supporting the local ecosystem and wildlife in the area.
Managed by the North Dakota State Water Commission, Solberg Dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. With a moderate risk level of 3, there is ongoing monitoring and risk management measures in place to ensure the safety and efficiency of the dam. Although the last inspection was conducted in 1999, the dam continues to be regulated, inspected, and permitted by the state authorities to maintain its integrity and functionality.
Located on Beaver Creek-TR, Solberg Dam is a significant structure in the region with a primary purpose of supporting fish and wildlife habitats. Despite its age, the dam has stood the test of time and remains an essential component of the local water resource management. As a point of interest for water resource and climate enthusiasts, Solberg Dam stands as a testament to the importance of sustainable water infrastructure for supporting ecological diversity and conservation efforts in North Dakota.

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 Solberg Dam; Dorvan
Where does the data for Solberg Dam; Dorvan 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.
