-Green River
Measuring juvenile salmon production from large river systems like the
Green River involves a tremendous amount of work. Key to developing
these estimates are the long hours of trap operation provided by our
dedicated scientific technicians: Bret Brown, Bob Green, and Paul Lorenz.
Logistical support was provided by Wild Salmon Production/Evaluation
Unit biologist Mike Ackley.
A number of other
individuals and agencies contributed to this project. For providing
access to the trap site, we thank the adjacent landowner Bill Mosby.
We also thank Mike Wilson, manager of the Soos Creek Hatchery, for providing
logistical support, office space and a secure staging site near the
trap.
-Dungeness River
WDFW scientific technicians Chris Burns, Joseph Boucher, Paul Lorenz,
Dan Phinney and Scott Schuetzler worked the long hours of trap operation;
their hard work and dedication was key to achieving our project goals.
Wild Salmon Production Evaluation Unit biologist, Mike Ackley and scientific
technician Brian Blazer provided logistical and technical support in
all areas of the project.
In addition, we
would like to thank the landowners of Dungeness Farms Inc., especially
caretaker Matt Heins, who gave us unrestricted access to their property
for trap placement and office trailer space, and provided power, water,
phone, tools, and general support, and landowners Ray Gorynski and Nash
Huber, who allowed us dike access to the trap site. We also thank Scott
Chitwood and Rodger Mosley, employees of the Jamestown S’Klallam
Tribe, for their contributions to this study, and Dan Witczak, manager
of the Hurd Creek Hatchery, for providing logistical support and an
office trailer.
-Cedar Creek
Skip Walch, Bao Le, Christina Luzier from the USFWS provided the CWT
tagging machine and screw trap for this study. Julie Grobelny, Josua
Holowatz, and Scott Nelson worked the trap during the 2005 field season.
Their field work was exceptional, and allowed for project goals to be
achieved. Additionally field staff were responsible for data entry,
which was accurate and timely. Jeff Grim analyzed the otoliths to determine
the number of coho salmon smolts collected that originated from a remote
site incubator (RSI). Michelle Groesbeck developed the database and
supplied the queries used in this analysis. Steve VanderPloeg created
the site map. Jim Scott reviewed an earlier draft of this report and
his comments improved this manuscript.

Executive Summary
Declining salmon populations
in the 1980s and 1990s resulted in the listing of a number of Washington
State salmon populations under the Endangered Species Act (ESA). Most
of these listings occurred between 1997 and 1999, impacting fisheries
and land management over the entire state. To better monitor the status
of these listed species and their production trends, the Washington
Department of Fish and Wildlife (WDFW) expanded its freshwater salmon
production monitoring (smolt monitoring) program. The new sites established
during this period included Cedar Creek in 1998 to monitor Lower Columbia
River steelhead, the Green River in 2000 and the Dungeness River in
2005 to monitor Puget Sound chinook. Funding for the Dungeness Chinook
Project was made possible through short-term (one-year) reserves from
the Agency General Fund monies. Continuation of this work has relied
on funding by the Salmon Recovery Funding Board (SRFB). The SRFB has
funded smolt monitoring on the Green River and Cedar Creek since 2002.
This annual report describes the smolt monitoring activities that
occurred on these three streams during the 2005 field season.
