Harrison is a private irrigation dam located in Lake Creek, Oregon, designed to regulate water from Lost Creek, Harrison Creek, and other streams in the area. Built in 1968, this earth dam stands at 27 feet high and stretches 760 feet in length, with a storage capacity of 500 acre-feet. Its primary purpose is irrigation, serving the agricultural needs of the region.

Managed by the Oregon Water Resources Department, Harrison Dam is state-regulated, inspected, and enforced for compliance. With its significant hazard potential, the dam is equipped with a slide (sluice gate) outlet gate and undergoes regular inspections every three years. While the dam's condition assessment is currently not rated, its emergency action plan status and risk management measures are yet to be fully assessed and documented.

In the event of a potential emergency, stakeholders in the area must ensure that the necessary protocols and guidelines are in place to address any risks associated with the dam's operation. As a vital resource for irrigation in Jackson County, Oregon, the Harrison Dam plays a crucial role in managing water resources and supporting agricultural activities in the region.
