Ben Lomond Reservoir dam
Ben Lomond Reservoir
Ben Lomond Reservoir, located in Weber, Utah, is a privately owned water body primarily used for irrigation purposes. Managed by the Utah Division of Water Rights, this earth dam structure stands at a height of 26 feet with a hydraulic height of 22.5 feet. The reservoir has a storage capacity of 22 acre-feet, with a normal storage level of 19.8 acre-feet.
With a significant hazard potential, Ben Lomond Reservoir is subject to regular inspections every five years. Despite not being rated for its condition assessment, the reservoir meets state regulatory requirements and is equipped with emergency action plans. The reservoir's spillway is 18 feet wide, capable of handling a maximum discharge of 12 cubic feet per second. The surrounding area is not at risk of inundation, and risk management measures are in place to address any potential hazards.
In the picturesque landscape of Ben Lomond Reservoir, water resource and climate enthusiasts can witness the harmonious blend of human engineering and natural beauty. With its vital role in sustaining local agriculture through irrigation, this reservoir serves as a testament to the importance of water management in ensuring a thriving ecosystem. As visitors explore the reservoir, they can appreciate the careful planning and maintenance efforts that go into safeguarding this essential water resource 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 Ben Lomond Reservoir
Where does the data for Ben Lomond 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.
