History of Our Office

What is now the Mid-Columbia Fish & Wildlife Conservation Office was established in 1974 under the authority of the Mitchell Act and the Anadromous Fish Conservation Act as the Fishery Assistance Office, Coulee Dam. The office provided technical fisheries assistance to the 1.3 million acre Colville Indian Reservation and to the Spokane Tribe. In 1976, the Colville Tribe hired their own fisheries biologists. In 1978, the Service office was moved to the Leavenworth National Fish Hatchery in Leavenworth, Washington, and was renamed the Fishery Assistance Office, Leavenworth National Fish Hatchery. The office assumed responsibility for evaluating hatchery fish production at the three hatcheries in the Leavenworth National Fish Hatchery Complex (Leavenworth, Entiat, and Winthrop National Fish Hatcheries). In addition, the office conducted field studies and prepared several reports summarizing production and status of several salmon species in the mid-Columbia River area and factors affecting their abundance. In 1990, the station was renamed the Mid-Columbia River Fishery Resource Office (MCRFRO) to better reflect the expansion of the fisheries program in eastern Washington. In 1998, a suboffice was established in Yakima, Washington, to coordinate activities related to flow issues and tribal trust responsibilities in the Yakima River Basin. In 2001, the office moved to larger facilities on the southeast grounds of the hatchery. In 2010 the Mid-Columbia River Fishery Resource Office was realigned to be part of the Leavenworth Fisheries Complex. The Complex also includes the Leavenworth, Entiat, and Winthrop National Fish Hatcheries. In 2016, the MCRFRO was re-named the Mid-Columbia Fish & Wildlife Conservation Office (MCFWCO). The scope of work of MCFWCO continues to evolve in response to declines in populations of native fish species, changes in roles and responsibilities, and changes in funding.
