Monticello City No. 1 dam
Monticello City No. 1
Monticello City No. 1 is a local government-owned dam located in San Juan, Utah, with a primary purpose of irrigation. Completed in 1975, this earth dam stands at a structural height of 30 feet and has a hydraulic height of 26 feet. The dam has a storage capacity of 135 acre-feet, with a normal storage level of 125 acre-feet, serving as a vital resource for water management in the region. Despite being labeled as low hazard potential, the dam is subject to state regulation, inspection, and enforcement by the Utah Division of Water Rights, ensuring its continued safety and functionality.
Situated near North Creek, Monticello City No. 1 plays a crucial role in the irrigation infrastructure of the area, supporting agricultural activities and water supply reliability. The dam spans 1600 feet in length and is designed to withstand the demands of water management in the region. While the dam's condition assessment is currently labeled as 'Not Rated,' regular inspections every five years help to monitor its performance and identify any necessary maintenance or improvements. With the dam's last inspection conducted in May 2016, efforts are ongoing to ensure its compliance with regulatory standards and emergency preparedness measures.
Managed by the Albuquerque District of the US Army Corps of Engineers, Monticello City No. 1 serves as a key component of the water resource infrastructure in Utah. With a dedicated purpose of irrigation, the dam contributes to the overall water management strategy in the region. Its strategic location and storage capacity make it an essential asset for maintaining water supply stability and supporting agricultural activities in the surrounding area. As climate change continues to impact water resources, the proper regulation and maintenance of dams like Monticello City No. 1 are critical to ensuring sustainable water management practices for future generations.
Dam data reference
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 Monticello City No. 1
Where does the data for Monticello City No. 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.
