Rob Roy dam
Rob Roy
Rob Roy is a fascinating earth dam located in Albany, Wyoming, specifically in the city of Keystone. Completed in 1986, this dam serves the primary purpose of water supply, supporting irrigation and water needs in the area. With a height of 140 feet and a structural height of 150 feet, Rob Roy boasts a storage capacity of 42,264 acre-feet, with a normal storage level of 35,434 acre-feet.
Situated on Douglas Creek, Rob Roy plays a crucial role in managing water resources in the region, with a drainage area of 20.8 square miles and a maximum discharge capacity of 4,500 cubic feet per second. The dam's spillway, which is uncontrolled, has a width of 30 feet, ensuring efficient flood control measures. Despite being assessed as having a fair condition, Rob Roy poses a high hazard potential, making regular inspections and maintenance vital to its continued operation.
Owned by the local government and regulated by the State of Wyoming, Rob Roy stands as a testament to human engineering and innovation in managing water resources and climate challenges. With its strategic location and impressive structural design, this dam serves as a vital asset in ensuring water supply reliability and mitigating potential risks associated with flooding. For water resource and climate enthusiasts, Rob Roy presents a compelling case study in sustainable water management practices and the critical role of infrastructure in adapting to changing environmental conditions.

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 Rob Roy
Where does the data for Rob Roy 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 High 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.
