Glendo Dike No. 3 dam
Glendo Dike No. 3
Glendo Dike No. 3, located in Wyoming along the North Platte River, is a federal-owned structure designed by I.J. Matthews for flood risk reduction. Completed in 1958, this earth dam stands at a height of 75 feet, with a total structural height of 88 feet and a hydraulic height of 61 feet. Its primary purpose is flood risk reduction, though it also serves hydroelectric and irrigation purposes.
With a storage capacity of 1,118,653 acre-feet and a surface area of 23,320 acres, Glendo Dike No. 3 plays a crucial role in managing water resources in the region. The dam has a high hazard potential and is regulated by the Bureau of Reclamation, which is also responsible for inspections and operations. Despite a moderate risk assessment rating, the condition assessment of the dam is currently listed as not available.
In 2016, the dam underwent modifications to its foundation, demonstrating a commitment to ensuring its structural integrity. While the dam does not have outlet gates, its uncontrolled spillway is designed to handle a maximum discharge of 21,535 cubic feet per second. Glendo Dike No. 3 stands as a key infrastructure for water resource management and climate resilience in Wyoming, showcasing the importance of effective dam regulation and maintenance in safeguarding communities from flood risks.

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 Glendo Dike No. 3
Where does the data for Glendo Dike No. 3 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.
