About this dam

Upper Hotel Lake

Upper Hotel Lake, located in Cedaredge, Colorado, is a privately owned reservoir primarily used for irrigation purposes. Built in 1886, this earth dam stands at a height of 15 feet and has a storage capacity of 190 acre-feet, with a normal storage level of 109 acre-feet. The dam, situated on Ward Creek, has a spillway width of 14 feet and a maximum discharge capacity of 475 cubic feet per second.

Despite being classified as low hazard potential and having a satisfactory condition assessment as of the last inspection in 2015, Upper Hotel Lake poses a high risk due to its location and design. With a drainage area of zero and a surface area of 14 acres, the reservoir serves both irrigation and recreational purposes. The dam's hazard potential level and risk assessment highlight the importance of ongoing monitoring and maintenance to ensure the safety and integrity of the structure in the face of changing climate conditions.

As water resources and climate enthusiasts, understanding the intricacies of Upper Hotel Lake's design, purpose, and risk profile provides valuable insight into the challenges and considerations associated with managing water infrastructure in a dynamic environment. With its historical significance and ongoing regulatory oversight, this reservoir serves as a reminder of the interconnectedness between human activities, natural resources, and climate impacts in shaping our water landscapes.

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.

FAQ

About Upper Hotel Lake

Where does the data for Upper Hotel Lake 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.
