Sundby No. 2 dam
Sundby No. 2
Sundby No. 2 is a privately owned earth dam located in Laramie, Wyoming, along Barkley Creek. Built in 1971 by designer John M Hill, this dam serves primarily for irrigation purposes but also provides fire protection, stock water, and functions as a small fish pond. With a height of 26 feet and a hydraulic height of 21 feet, it has a storage capacity of 45 acre-feet and a surface area of 3 acres.
Despite its low hazard potential, Sundby No. 2 is in poor condition according to its last inspection in 2019. The dam has an uncontrolled spillway with a width of 8 feet and a single valve outlet gate. While the risk assessment categorizes it as moderate, there are no current risk management measures in place. The dam's condition assessment, coupled with its outdated inspection frequency of 5 years, raises concerns among water resource and climate enthusiasts about its long-term sustainability and safety.
Given its crucial role in supporting agriculture and providing water resources in the area, stakeholders may need to prioritize maintenance and upgrades to ensure the structural integrity and functionality of Sundby No. 2. With its location in a scenic part of Albany County, Wyoming, this dam serves as a reminder of the delicate balance between human needs and environmental conservation in the face of changing climate patterns and increasing water demands.
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 Sundby No. 2
Where does the data for Sundby No. 2 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.
