Alkali Creek dam
Alkali Creek
Alkali Creek in Wyoming is a privately-owned irrigation dam completed in 1950, serving multiple purposes including fire protection, stock, and small fish ponds. The earth dam stands at a height of 36 feet, with a hydraulic height of 31 feet and a length of 685 feet. The dam has a storage capacity of 114 acre-feet, with a normal storage level of 66 acre-feet, covering a surface area of 8 acres and draining a 5.3 square mile watershed.
Despite being classified as having a low hazard potential, Alkali Creek's condition assessment is rated as poor, indicating a potential need for maintenance or repair. The last inspection in 2019 noted this assessment, and the dam is subject to regular inspections every 5 years. The spillway is uncontrolled with a width of 20 feet, and the outlet gates consist of two valves. The risk assessment for Alkali Creek is moderate, signaling a need for ongoing risk management measures to ensure the dam's safety and integrity in the face of potential climate and water resource challenges.
Located in Park County, Wyoming, Alkali Creek serves as a vital resource for irrigation in the region. The dam's proximity to the city of Byron underscores its importance in supporting local agriculture and water management efforts. With the dam's historical significance dating back over 70 years, continued monitoring and maintenance will be essential to ensure the long-term sustainability and effectiveness of Alkali Creek in the face of changing climate conditions and evolving water resource needs in the region.
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.

About Alkali Creek
Where does the data for Alkali Creek 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.
