Magna Reservoir dam
Magna Reservoir
Magna Reservoir, located in Salt Lake, Utah, is a privately owned water resource managed by the Utah Division of Water Rights. With a primary purpose of irrigation, this Earth dam structure stands at a hydraulic height of 9.5 feet and a structural height of 10 feet. The reservoir has a storage capacity of 9.96 acre-feet and a length of 571 feet, making it a significant water source for the surrounding area.
Despite not having a designated completion year or a current condition rating, Magna Reservoir is classified as having a significant hazard potential. With a spillway width of 10 feet and a maximum discharge of 13 cubic feet per second, the reservoir plays a crucial role in managing water flow and irrigation needs in the region. The structure is subject to regular inspections and falls under state jurisdiction for permitting, inspection, and enforcement, ensuring its operational safety and compliance with regulations.
Water resource and climate enthusiasts are drawn to Magna Reservoir for its vital role in supporting agricultural activities in the area. As a key component of the local water infrastructure, the reservoir serves as a strategic water storage facility, contributing to the sustainability of irrigation practices and water management in the region. Despite its condition assessment being listed as "Not Rated," the reservoir's importance in water resource management and its significant hazard potential make it a focal point for ongoing monitoring and maintenance efforts.

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 Magna Reservoir
Where does the data for Magna 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.
