American Fork Lower Reservoir dam
American Fork Lower Reservoir
American Fork Lower Reservoir, located in American Fork, Utah, is a privately owned water resource managed by the Utah Division of Water Rights. Built in 2009 by Franson Civil, this earth dam stands at a structural height of 25 feet and has a hydraulic height of 22 feet. With a storage capacity of 34.1 acre-feet, the reservoir primarily serves irrigation purposes, supporting agricultural activities in the region.
The dam has a significant hazard potential but is currently in satisfactory condition, last assessed in April 2009. Regular inspections are conducted every two years to ensure its safety and structural integrity. The reservoir boasts a maximum discharge of 59 cubic feet per second, with a spillway width of 7 feet. Situated within the Omaha District, this water source plays a crucial role in water management and conservation efforts in the area.
Enthusiasts of water resources and climate will find American Fork Lower Reservoir to be a fascinating site, showcasing the intersection of human engineering with natural ecological systems. As a vital component of the local irrigation infrastructure, this reservoir demonstrates the importance of sustainable water management practices in the face of changing climate patterns. With its strategic location and significant storage capacity, the reservoir serves as a key resource for the community, highlighting the critical role of water resources in maintaining agricultural productivity and ecosystem health in the region.
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 American Fork Lower Reservoir
Where does the data for American Fork Lower Reservoir 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 Significant 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.
