Mount Gunnison #1-Fw 1 dam
Mount Gunnison #1-Fw 1
Mount Gunnison #1-Fw 1, also known as Arco Fw #1, is a privately owned earth dam located in Gunnison, Colorado. Completed in 1982, this dam stands at 26 feet tall and stretches 500 feet in length, with a primary purpose of water supply. The dam is situated on the North Fork Gunnison River-OS and has a maximum storage capacity of 16 acre-feet, with a normal storage level of 10 acre-feet.
Despite its low hazard potential and satisfactory condition assessment, Mount Gunnison #1-Fw 1 is classified as high risk due to its risk assessment rating of 2. The dam features slide (sluice gate) and uncontrolled outlet gates, and has a spillway width of 10 feet. The last inspection of this dam was conducted in October 2018, with a mandated inspection frequency of 6 years. While there are no associated structures with this dam, it plays a crucial role in water resource management for the surrounding area.
Water resource and climate enthusiasts would be intrigued by the intricacies of Mount Gunnison #1-Fw 1, from its design and construction details to its operational and regulatory aspects. This dam serves as a vital component of the water supply infrastructure in Gunnison, Colorado, highlighting the importance of proper maintenance and inspection protocols to ensure its continued functionality and safety. As discussions surrounding water resource management and climate change intensify, the role of dams like Mount Gunnison #1-Fw 1 becomes increasingly significant in addressing the challenges of a changing environment.

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 Mount Gunnison #1-Fw 1
Where does the data for Mount Gunnison #1-Fw 1 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.
