Krs No. 3 dam
Krs No. 3
Krs No. 3, located in Natrona, Wyoming, is a federal-owned earth dam completed in 1996 with a primary purpose of fire protection, stock, or small fish pond. This dam on the South Fork Hackett Creek stands at a height of 25 feet and has a structural height of 28 feet, with a storage capacity of 71 acre-feet. With a low hazard potential and fair condition assessment, Krs No. 3 serves the community as a vital structure for flood risk reduction and water resource management.
Managed by the Sacramento District of the US Army Corps of Engineers, Krs No. 3 has a spillway width of 40 feet and an outlet gate with a valve for controlled water release. The dam's drainage area is 0.95 square miles, covering a surface area of 3.97 acres. Despite its moderate risk assessment rating, Krs No. 3 is regularly inspected every five years to ensure its continued safe operation and maintenance. The presence of state regulation and enforcement further enhances the dam's role in protecting the surrounding area from potential water-related emergencies.
In the event of an emergency, Krs No. 3's emergency action plan (EAP) status and risk management measures are currently undisclosed. However, with its strategic location near I-25 and effective emergency contacts, this dam remains a crucial asset for water supply, fire protection, and environmental conservation in the region. Climate enthusiasts and water resource advocates can appreciate Krs No. 3 for its multi-faceted benefits and essential role in safeguarding the local community against water-related risks and challenges.

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 Krs No. 3
Where does the data for Krs No. 3 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.
