Krogh Dam; Clarence 4 dam
Krogh Dam; Clarence 4
Krogh Dam, also known as Clarence 4, is a private-owned Earth dam located in Hettinger, North Dakota. Constructed in 1996 by the USFWS, this dam serves as a Fish and Wildlife Pond, providing essential habitat for aquatic life in the area. With a height of 8.8 feet and a length of 318 feet, Krogh Dam has a maximum storage capacity of 80.4 acre-feet and a normal storage capacity of 12.4 acre-feet.
The dam is regulated by the NDSWC and is subject to state permitting, inspection, and enforcement. Despite being classified as having a low hazard potential, Krogh Dam is considered to have a moderate risk level. It has an uncontrolled spillway with a width of 55 feet and is situated on Indian Creek-TR. Although the dam has not been rated for its condition, it is not currently deemed to pose a significant threat.
Overall, Krogh Dam plays a vital role in the local ecosystem by providing a suitable environment for fish and wildlife. Despite its moderate risk level, the dam is well-maintained and closely monitored to ensure the safety of the surrounding community and the integrity of the structure. Its presence contributes to the conservation efforts in the area and serves as a valuable resource for water and climate enthusiasts.

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 Krogh Dam; Clarence 4
Where does the data for Krogh Dam; Clarence 4 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.
