Andreasen Upper dam
Andreasen Upper
Andreasen Upper, located in Franklin, Idaho, is a privately owned dam constructed in 1957 primarily for irrigation purposes. The dam stands at a height of 28.8 feet and has a hydraulic height of 10 feet, with a storage capacity of 40 acre-feet and a surface area of 6 acres. The dam is built using earth and stone materials, with rock and soil foundations, and is situated on an unnamed stream flowing into Battle Creek.
Despite its significant hazard potential and unsatisfactory condition assessment, Andreasen Upper is regulated by the Idaho Department of Water Resources and undergoes regular state inspections, permitting, and enforcement. The dam features an uncontrolled spillway type with a width of 10 feet and outlet gates in the form of slide (sluice gate). The dam's risk assessment is classified as moderate (3), indicating a need for continued risk management measures to ensure the safety and stability of the structure.
Overall, Andreasen Upper serves as a vital water resource for irrigation in the region, but its condition and hazard potential warrant ongoing attention and maintenance to mitigate risks and ensure the safety of downstream communities and ecosystems. This dam stands as a reminder of the importance of effective dam management practices in the face of changing climate conditions and increasing water resource demands.

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 Andreasen Upper
Where does the data for Andreasen Upper 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.
