Aeree Dam
Aeree
Located in Folsom, California, Aeree is a privately owned earth dam primarily used for water supply purposes, serving irrigation and water supply needs in the area. Standing at a height of 35 feet with a hydraulic height of 29 feet, Aeree was completed in 1951 and has a storage capacity of 90 acre-feet. The dam spans 905 feet in length and sits on Tr Pilot Creek, within El Dorado County.
Managed by the California Department of Water Resources and regulated by the Safety of Dams division, Aeree is subject to regular state inspections and enforcement to ensure its structural integrity and compliance with safety standards. With a hazard potential classified as 'Significant' and a condition assessment deemed 'Satisfactory' as of September 2017, the dam has emergency action plans in place, although their last revision was in December 2020.
Due to its critical role in water resource management, Aeree serves as a vital infrastructure component in the region, requiring ongoing monitoring and maintenance to mitigate risks and safeguard the surrounding communities from potential hazards. As a key feature in the local water supply network, Aeree represents a fusion of engineering ingenuity and environmental stewardship, contributing to the sustainable use of water resources amidst changing climatic conditions.

About Aeree
Where does the data for Aeree 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.

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.
