Hyatt dam
Hyatt
Hyatt, also known as H-2, is a federal-owned water resource located in Oregon, specifically in Jackson County. This hydroelectric facility, managed by the Bureau of Reclamation, serves multiple purposes including hydroelectric power generation, irrigation, and recreation. The dam, completed in 1921, is a rockfill structure standing at 53 feet high with a storage capacity of 25,100 acre-feet.
The Hyatt dam on Keene Creek has a spillway width of 50 feet and a hazard potential rated as high. With a moderate risk assessment, the facility underwent modifications in 2017 to address foundation and structural concerns. Despite its age, Hyatt remains a key asset in water resource management in the region with a normal storage capacity of 16,200 acre-feet and a surface area of 1,120 acres. As a popular destination for recreational activities, Hyatt plays a vital role in balancing water supply needs with environmental conservation efforts in Oregon.
With its historic significance and ongoing management by the Bureau of Reclamation, Hyatt continues to be a focal point for water resource and climate enthusiasts interested in sustainable hydroelectric power generation, irrigation practices, and recreational opportunities in the region. The facility's critical role in water management, coupled with its engineering complexity and scenic location, makes Hyatt a fascinating subject for those passionate about the intersection of water resources, climate resilience, and sustainable development.

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 Hyatt
Where does the data for Hyatt 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.
