Morrison, also known as Legacy Ranch, is a privately owned water resource in Franklin, Idaho. This dam was completed in 1959 and serves primarily for irrigation purposes, with a storage capacity of 65.52 acre-feet. Situated on an unnamed stream called Spring Creek, Morrison is regulated by the Idaho Department of Water Resources, with state permitting, inspection, and enforcement in place. The dam is classified as an earth dam with a height of 17 feet and a spillway width of 6 feet.

Despite being categorized as low hazard potential, Morrison has a very high risk assessment rating, indicating potential vulnerabilities that may require attention. The dam's condition was assessed as fair during the last inspection in July 2017, with an inspection frequency of 5 years. The surrounding area has a drainage area of 0.4 square miles and a surface area of 12.6 acres. With its location in a region prone to climate variability, water resource and climate enthusiasts may find Morrison's data and risk profile to be of particular interest for further study and monitoring.
