Payette Lake Upper, also known as Upper Payette Lake Dam, is a privately owned structure located in McCall, Idaho. Completed in 1953, this concrete dam serves primarily for irrigation purposes, with a storage capacity of 2400 acre-feet and a surface area of 315 acres. The dam stands at a height of 15 feet, with an uncontrolled spillway width of 30 feet and a maximum discharge capacity of 1070 cubic feet per second.

Situated on the North Fork Payette River, Payette Lake Upper is regulated by the Idaho Department of Water Resources, with regular inspections and enforcement measures in place to ensure its safety and functionality. The dam's hazard potential is considered significant, with a fair condition assessment as of the last inspection in July 2018. Despite its moderate risk level, the dam plays a crucial role in water management and irrigation in the region, making it a vital asset for water resource and climate enthusiasts to monitor and study.
