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.
