Dvorak Dam; David dam
Dvorak Dam; David
Dvorak Dam, also known as David Dam, is a privately owned structure located in Dunn County, North Dakota. Completed in 1987, this earth dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 12 feet and a length of 200 feet, the dam has a storage capacity of 51.4 acre-feet and covers a surface area of 6.7 acres. It is regulated by the North Dakota State Water Commission (NDSWC) and is equipped with an uncontrolled spillway that is 100 feet wide.
Despite its low hazard potential and moderate risk assessment, Dvorak Dam has not been inspected since October 2000, with its condition currently marked as "Not Rated". The dam is not equipped with outlet gates and does not have an Emergency Action Plan (EAP) in place. Although its risk management measures are unspecified, it remains under state jurisdiction and is subject to regular permitting, inspection, and enforcement by the NDSWC. Situated on Crooked Creek-TR, this dam plays a crucial role in water resource management and ecosystem support within the region.
For water resource and climate enthusiasts, Dvorak Dam presents a unique opportunity to study a privately owned structure that contributes to the local ecosystem's health and sustainability. As one of the many dams in North Dakota regulated by state agencies, Dvorak Dam highlights the importance of regular inspection, maintenance, and risk assessment to ensure the safety and functionality of such water infrastructure. Its role in providing fire protection, stock watering, and recreational opportunities underscores the diverse benefits that well-managed dams can offer to both humans and wildlife in the area.

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 Dvorak Dam; David
Where does the data for Dvorak Dam; David 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.
