Introductory letter sent October 20, 2004
Dear Interested Party:
The Council and NOAA Fisheries will sponsor a two-day symposium
November 9-10 at the Council headquarters in Portland, beginning at 10am
on the 9th, to examine the relationship between river flows and survival
of juvenile and adult anadromous fish. The Council's Columbia River
Basin Fish and Wildlife Program proposes a hypothesis that certain
modifications to current operations at Libby and Hungry Horse dams would
significantly benefit resident fish without discernable adverse effects on
the survival of juvenile and adult anadromous fish. The flow-survival
issue is at the heart of that hypothesis.
A number of experts have been invited to make presentations and engage
in discussions at the symposium, which is open to the public. This letter
is not an invitation to make a presentation at the symposium, but a notice
that the symposium will take place and an invitation to attend as an
audience member.
The symposium responds to a recommendation from Bob Lohn, regional
director of NOAA Fisheries (see attached letter), that NOAA Fisheries and
the Council work together to identify the present bounds of science
regarding flows and fish survival. Specifically, Mr. Lohn suggested that
the Council, NOAA Fisheries and interested Columbia River tribes or tribal
organizations sponsor a scientific symposium or workshop to address issues
relating to the science of river flows and fish survival. These have been
distilled to the following points for the symposium:
- What is the state of the science between flows and juvenile
survival? Where is there consensus and where is there disagreement?
- Which attributes that are unknown are most important in making hydro
decisions? What kind of research would be needed to resolve
them?
- Is there an experimental design practical and feasible to test how
changes in reservoir operations can affect fish in the lower river? If
so, how would the experiment be structured?
- In modeling projected effects of flow on listed and non-listed fish,
what are the relative strengths and weaknesses of the available
models? Is there credible scientific information that certain
models and assumptions are likely to be more reliable than others?
I hope you will be able to attend the symposium. Please let Kendra
Phillips know if you plan to attend, either at 800-452-5161 or
by October 29, 2004.
Sincerely,
Stephen L. Crow, Executive Director
