Egbert Dam dam
Egbert Dam
Egbert Dam, located in Fremont, Idaho, along the Spring Creek section of Henrys Fork, serves primarily for irrigation purposes. Built in 1982, this earth dam with a stone core stands at a height of 15.4 feet, providing a storage capacity of 70 acre-feet. The dam spans a length of 525 feet and has a spillway width of 13 feet, allowing for a maximum discharge of 87 cubic feet per second.
Managed by a private owner, Egbert Dam is regulated by the Idaho Department of Water Resources, ensuring state oversight for its operations, inspections, and enforcement. Despite its low hazard potential and fair condition assessment, the dam has a moderate risk rating of 3, warranting attention to risk management measures. Its last inspection in July 2017 indicated compliance with safety guidelines, with an inspection frequency of 5 years.
Water resource and climate enthusiasts interested in the infrastructure of Egbert Dam will find its location in the Ashton Reservoir area intriguing. As part of the irrigation network in the region, the dam plays a crucial role in water management for agricultural activities. With its proximity to the scenic Henrys Fork, the dam also contributes to the ecological balance of the area. Overall, Egbert Dam stands as a testament to the collaboration between private ownership and state regulation in safeguarding water resources in Idaho's landscape.

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 Egbert Dam
Where does the data for Egbert Dam 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.
