Hyatt dam
Hyatt
Hyatt, located in Arvada, Colorado, is a privately owned dam that serves primarily for irrigation purposes. Built in 1863, this earth dam stands at 22 feet tall with a hydraulic height of 18 feet and a structural height of 24 feet. The dam has a storage capacity of 1000 acre-feet, with a normal storage level of 760 acre-feet and a surface area of 73 acres. The dam is situated on the Van Bibber Creek-TR river.
Despite its historical significance, Hyatt poses a high hazard potential and has an unsatisfactory condition assessment. The dam's spillway is uncontrolled with a width of 35 feet, and it has a maximum discharge rate of 625 cubic feet per second. The dam has been inspected annually, with the last assessment conducted on June 26, 2020. With a risk assessment rating of moderate (3), there are potential risks associated with the dam that need to be addressed to ensure the safety of the surrounding community.
In terms of regulation, Hyatt is under the jurisdiction of the Colorado Department of Water Resources and is subject to state permitting, inspection, and enforcement. The dam is not owned or funded by any federal agencies, and there are no associated structures or locks. With its historical significance and crucial role in irrigation, the management and maintenance of Hyatt are essential to mitigate potential risks and ensure the sustainable use of water resources in the region.

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.
