Government No. 1 Stock dam
Government No. 1 Stock
Government No. 1 Stock is a private water resource in Wyoming, specifically located in Johnson County near the city of Arvada. Built in 1962, this earth dam stands at a height of 30 feet and serves multiple purposes including fire protection, stock usage, and as a small fish pond. The dam has a storage capacity of 26 acre-feet and covers a surface area of 20 acres, drawing water from the South Prong No. 1 Draw.
Despite its low hazard potential, Government No. 1 Stock has been assessed to be in poor condition, with the last inspection taking place in May 2018. The dam's spillway is uncontrolled with a width of 20 feet, and it is regulated by the State of Wyoming with inspections, permitting, and enforcement measures in place. The dam is situated in a scenic location and provides essential services for the local area, making it an important asset for water resource and climate enthusiasts to monitor and support in the future.
As a vital component of the local water infrastructure, Government No. 1 Stock plays a crucial role in maintaining water resources for fire protection, livestock, and recreational purposes. With a moderate risk assessment rating, there is a need for ongoing risk management and maintenance measures to ensure the dam's continued functionality and safety. Climate and water resource enthusiasts should take note of this dam's significance in the region and advocate for proper upkeep and monitoring to preserve its valuable contributions to the community and environment.

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 Government No. 1 Stock
Where does the data for Government No. 1 Stock 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.
