Riverton Dam -Formerly American Contract Dam
Riverton Dam -Formerly American Contract
Riverton Dam, formerly known as American Contract, is a private-owned structure located in the city of THE JORDAN RIVER, Salt Lake County, Utah. The dam is regulated by the Utah Division of Water Rights and is subject to state inspection and enforcement. With a hydraulic height of 12 feet and a structural height of 15 feet, Riverton Dam has a significant hazard potential and is classified as not rated in terms of its condition assessment.
Constructed for unknown primary purposes, Riverton Dam has a storage capacity of 18 acre-feet, with a normal storage level of 15 acre-feet. The dam is situated on an unknown river or stream, with a drainage area of 595 square miles. Despite its age and lack of recent condition assessment, Riverton Dam remains a crucial infrastructure for water resource management in the region. However, the lack of information on its design, construction, and modifications raises questions about its long-term reliability and safety.
With the potential to impact surrounding communities in case of failure, Riverton Dam requires regular inspections and a comprehensive emergency action plan to mitigate risks. The dam's current status as not rated in terms of condition assessment underscores the need for further evaluation and maintenance to ensure the safety and resilience of this vital water resource infrastructure in Utah.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Riverton Dam -Formerly American Contract
Where does the data for Riverton Dam -Formerly American Contract 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 below 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.
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.
