Located in Idaho's Valley County, Knox Meadow, also known as Cruickshank Reservoir, is a privately owned water resource that serves primarily for irrigation purposes. Built in 1941, this earth dam structure stands at a height of 18.5 feet, with a hydraulic height of 12.8 feet, providing a storage capacity of 1,073 acre-feet. The reservoir covers a surface area of 156 acres and is situated on an unnamed stream in Lake Fork, contributing to a drainage area of 1.4 square miles.

With a spillway designed for controlled release, Knox Meadow has a spillway width of 7 feet and a maximum discharge rate of 63 cubic feet per second. Despite being classified as having a significant hazard potential, the dam is currently in fair condition as of its last inspection in May 2017. The risk assessment for this structure indicates a very high risk level, emphasizing the importance of ongoing maintenance and monitoring to ensure the safety and integrity of the reservoir. Water resource and climate enthusiasts will find Knox Meadow to be an intriguing example of human-made infrastructure supporting agricultural activities in Idaho's rural landscape.
