Stonebridge dam
Stonebridge
Stonebridge, located in Wapatia, Wyoming, is a privately owned irrigation dam constructed in 1905 by designer Roy R. Holm. This earth dam, with a height of 24 feet and a length of 685 feet, serves the primary purpose of irrigation along the Whit Creek offstream. Stonebridge has a storage capacity of 822 acre-feet, with a surface area of 63 acres and a drainage area of 1 square mile.
Despite being regulated by the State of Wyoming, Stonebridge is classified as having a significant hazard potential with a fair condition assessment. The dam features an uncontrolled spillway with a width of 50 feet and is equipped with valve gates for outlet control. The last inspection in July 2017 revealed a moderate risk level (3) and an inspection frequency of every 5 years. Stonebridge remains an essential structure for water resource management in the region, providing crucial irrigation support for agricultural activities.
As a key component of the local water infrastructure, Stonebridge plays a crucial role in ensuring water availability for the surrounding area. With its historical significance and ongoing importance for irrigation purposes, the dam represents a blend of engineering ingenuity and environmental stewardship. Climate enthusiasts and water resource experts alike can appreciate the intricate balance of water management and conservation efforts embodied by Stonebridge in Park County, Wyoming.

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 Stonebridge
Where does the data for Stonebridge 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.
