Kiewit Herbs Creek No. 1 Dam
Kiewit Herbs Creek No. 1
Kiewit Herbs Creek No. 1, also known as Herb's Creek Dam No. 1, is a privately owned earth dam located in Sheridan, Wyoming. Completed in 1967, this dam serves primarily for irrigation purposes, with a storage capacity of 98 acre-feet. Situated on the Herb Creek, a tributary of Gay Creek, the dam stands at a height of 44 feet and has a length of 425 feet, providing water resources for a drainage area of 3.3 square miles.
With a low hazard potential and fair condition assessment, Kiewit Herbs Creek No. 1 is regulated by the State of Wyoming, with inspections and enforcement carried out by the State Engineer's Office. The dam features an uncontrolled spillway with a width of 50 feet and an outlet gate for water control. Despite its moderate risk assessment, the dam has not undergone any modifications in recent years and has an inspection frequency of 5 years to ensure its continued functionality.
Water resource and climate enthusiasts will appreciate the role of Kiewit Herbs Creek No. 1 in providing water for irrigation, fire protection, and wildlife habitat in the region. Its location in the scenic surroundings of Sheridan, Wyoming, and the moderate risk it poses make it a significant structure for water management and conservation efforts in the area.

About Kiewit Herbs Creek No. 1
Where does the data for Kiewit Herbs Creek No. 1 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 below 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.
Dam data reference
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.
