Summary
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.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
