Entiat Hatchery Tours Begin
It’s not too early to schedule an Entiat Hatchery tour for this upcoming spring and summer. Tours are available Monday – Friday between 10 am and 2 pm each day. Scheduling ahead provides hatchery staff time to plan and customize a special tour just for your school, organization, business, or community group. It’s a great way for us to connect you with nature!
Tours include a walk in the visitor center and hatchery nursery providing several opportunities to view salmon. Also included, is a beautiful stroll on the scenic Red Willow Trail which follows the Entiat River where you can observe wildlife and enjoy the smell and sounds of nature at its best. Bring a picnic and relax by the hatchery’s Brock Pond. Call 509-784-1131 for more information.
Current Projects
Entiat National Fish Hatchery Review
The U.S. Fish and Wildlife Service (Service) proactively initiated a series of hatchery reviews in May 2005 to assure that its 21 hatchery programs are part of a holistic and integrated strategy—consistent with State, Tribal, and Federal strategies—for conserving wild stocks and managing fisheries in watersheds within the Columbia River Basin. These reviews were tailored after a successful process recently implemented in Puget Sound and Coastal Washington watersheds.
The team completed their review of the Entiat National Fish Hatchery (NFH) program in April 2007.
The Hatchery Review Team, comprised of Service and other federal scientists (NOAA & USGS) conducted field tours with hatchery managers and their staffs, reviewed hatchery operations, and met the co-managing agencies and tribes to get a clear understanding of the goals for and status of each wild and hatchery population and their associated habitat and management strategies. Following these field visits, the team put together recommendations for each hatchery which were then documented in the Pacific Region Hatchery Review Team Report. See the Entiat National Fish Hatchery section in the Leavenworth Complex Review Final Report.
Both NOAA Fisheries, the federal agency responsible for salmon recovery and the Service’s Hatchery Review team concluded that the Entiat NFH produced spring Chinook salmon which posed an unnecessary risk to the listed spring Chinook stocks. At the same time, this hatchery stock has provided little benefit to sport fishing anglers in the local Entiat River area. To eliminate the risk to listed spring Chinook salmon stocks, the Entiat NFH spring Chinook salmon program has been phased out. Transitioning to a coho program to support coho restoration in the Upper Columbia Basin is being evaluated closely along with other possible alternative programs in a way that minimizes adverse impacts to local stocks.

Spring Chinook Salmon Phase-Out and Coho Salmon Production Program Feasibility
Currently, the Entiat hatchery is rearing a 250K coho program. Following the 2007 Hatchery Review, the Review Team recommended replacement of the spring Chinook salmon. This program is in a “test” or feasibility phase. The purpose of the test phase is; 1) to test the suitability of surface water (Entiat River) in rearing coho salmon (Oncorhynchus kisutch) at Entiat National Fish Hatchery (ENFH); 2) to determine the extent and time of greatest infection of juvenile coho salmon to the Myxobolus parasite present in the Entiat River.
A Myxobolus parasite was first documented in juvenile spring Chinook salmon (Oncorhynchus tshawytscha; SCS) raised in Entiat River water around 1986 at ENFH. The parasite caused considerable damage to the spinal cord and brainstem of infected juvenile SCS resulting in increased mortality and reduced fitness for survival outside of hatchery environs. The condition known as tail rot was the first visual sign, aside from high mortality, of infected fish. Other signs included emaciation and spinal deformities.
Fish health parameters will be measured throughout the rearing cycle. 200k of the 250k coho will be reared on well/spring water and released into the Wenatchee River in spring 2009. 50K will be raised on Entiat River water (release site TBD). Concurrently, when released in 2009, 200k of the 250k coho will contribute to the Yakama Nation’s Mid-Columbia Coho Reintroduction Feasibility Project.

The Yakama Nation Mid-Columbia Coho Reintroduction Feasibility Project
Coho Salmon (Oncorhynchus kisutch)
The Entiat National Fish Hatchery (NFH) supports the Mid-Columbia Coho Reintroduction Feasibility Project led by the Yakama Indian Nation. The purpose of the project is to reintroduce coho salmon into the mid-Columbia River basin tributaries. The project takes place in the Methow and Wenatchee river basins in Chelan and Okanogan counties. The Entiat NFH provides a location for this project to hold, spawn, and incubate coho salmon.

Habitat Improvement Project
The Entiat National Fish Hatchery is embarking on a special project to improve habitat for fish in the Entiat River. The Entiat River was identified as one of several priority river sub-basins by the National Marine Fisheries Service in the latest Federal Columbia River Power System Biological Opinion. The Bureau of Reclamation is providing technical assistance to improve survival of threatened and endangered species. This partnership project and the preliminary planning report are in their very early stages.
The report will describe the components of the project as it is located at the Entiat National Fish Hatchery. The design objective is to provide off-channel habitat for fish, several wetland ponds, with one to be used as children’s fishing pond. A key component of this site is also to provide an aesthetically pleasing natural place for the public to recreate and enjoy the surrounding environmental resources along the river.

Red Willow Trail
The Entiat National Fish Hatchery has worked closely with the Washington State 4-H Forestry Summer High School Program during the past few years to lay-out and construct the Red Willow Trail along the Entiat River. The students will be continuing to maintain and extend the trail during the upcoming summers to create a level loop walk that can be enjoyed by all ages. Working with hatchery staff and other partners, these students are building a unique nature experience connecting people with nature. Bring your family for wildlife viewing and an enjoyable walk.

Pacific Lamprey
The Pacific Lamprey is a primitive fish species that has wide distribution in the Pacific Northwest. Information on this species is limited and indicates that their numbers are declining. Counts of lamprey at the Columbia River Dams show a decline in numbers of lamprey migrating up the Columbia River. They are a “species of concern”, with four species of lamprey (Pacific lamprey, Lampetra tridentata, western brook lamprey L. richardsoni, river lamprey L. ayresi, and L. hubbsi) being petitioned for listing under the Endangered Species Act.
Information about the presence of lamprey has been gathered at the Entiat River rotary screw traps and while performing snorkel and electrofishing work. In 2007, the Mid-Columbia River Fisheries Resource Office and the Entiat National Fish Hatchery staff began a multi-year study to investigate lamprey use of the hatchery pollution abatement pond.
