Cedar River

HatcheryPAST TO PRESENT

Sockeye Salmon life history stages

• Cedar River Hatchery Timeline

1991: Interim Hatchery operation begins in co-manager

response to low abundance of Cedar River Sockeye. Gillnets

utilized to collect broodstock

1993: Interim Hatchery capacity upgraded to 9 million with

addition of Kitoi incubators; first in-river weir installed near

Cavanaugh Ponds (RM 6.4)

1996: 28 Kitoi incubators added to increase total eggtake

potential to 18.7 million

2001: First year of sockeye fry feeding experiment initiated

2002: First year of IHNV detected in hatchery incubators

2008: New collection site at RM 1.7 in Renton, first year of all

sockeye releases being fed prior to release

2011: New permanent Hatchery completed and operational;

138 Kitoi incubators, fry release goal of 34 million

2012: Most eggs taken to date, 20+ million

Interim Sockeye Hatchery 1991-2010

Interim Hatchery Primary Achievements

Slow rate of decline in sockeye by augmenting fry

production

Test and perfect the efficacy of recently developed

sockeye culture techniques (Incubation, feeding

experiments, IHNV disinfection protocols)

Provide large number of differentially marked fish to

support the Lake Washington studies (in-river fry, lake

pre-smolt and smolt survival; percent hatchery

contribution to adult return)

Provided opportunity for sport fisheries in 2002, 2004, and

2006

Permanent Cedar River Hatchery completed and operational

on September 26, 2011

Facility owned and funded by Seattle Public Utilities, operated

by Washington Department of Fish and Wildlife

Permanent Hatchery Managed under the Adaptive Management Plan

Defines an operating and management framework for the hatchery

First Goal: Operate a biologically and environmentally sound long

term program that will provide for the recovery and persistence of a

well adapted, genetically diverse, healthy, harvestable population

of Cedar River sockeye

Second Goal: Avoid or reduce detrimental effects on the

reproductive fitness and genetic diversity of naturally reproducing

salmon populations in the Cedar River

Success of the hatchery, and its ability to provide fisheries, is

dependent on the health and productivity of the natural run. Both

are necessary for success!

Weir is managed for two equally important goals: Collect sockeye

broodstock and minimize impacts to Chinook

Broodstock Collection Weir: Limiting

Factors

Susceptible to high flows, which can limit collection capability

during prime fish movement and migrational times

Must be removed before flood events or it will be severely

damaged, which is typically in early to mid November, sometimes

sooner

Must be managed under Chinook Protocols with the goal of no

significant delay to upstream Chinook migration (ESA listed stock)

Seattle Public Utilities is currently working with a consultant and

funding a design for a new weir to address some of these limitations
