Wyoming Hereford Ranch No. 1 dam
Wyoming Hereford Ranch No. 1
Wyoming Hereford Ranch No. 1 is a private irrigation dam located in Laramie, Wyoming, along Crow Creek. Built in 1930 by designer Henry Lloyd, this earth dam stands at 28 feet high with a length of 1300 feet, providing a storage capacity of 1622 acre-feet for agricultural purposes. The dam, constructed with stone core and soil foundation, serves as a vital water resource for the surrounding area, with a normal storage capacity of 878 acre-feet and a maximum discharge rate of 7180 cubic feet per second.
Despite its age, Wyoming Hereford Ranch No. 1 remains in fair condition as of the last inspection in September 2021, with a significant hazard potential due to its location and design. The dam is equipped with an uncontrolled spillway, 4 vertical lift outlet gates, and a spillway width of 1700 feet to manage potential flooding events. With a drainage area of 318 square miles and a surface area of 109 acres, this dam plays a crucial role in water management and irrigation for the local agricultural community. Overall, Wyoming Hereford Ranch No. 1 represents a key piece of infrastructure in maintaining water resources and supporting the climate-resilient practices of 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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Wyoming Hereford Ranch No. 1
Where does the data for Wyoming Hereford Ranch 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 Significant 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.
