At our last meeting on June 24 at Packwood, discussions
were held between Energy Northwest and the natural resource agencies and tribes
regarding refinements and clarifications to the draft 401 Water Quality
Certification, Instream Flow, and Habitat Assessment protocols. Comments on the drafts have also been
received and reviewed. Following is a
brief summary of items that were discussed and what Energy Northwest plans to
include in the studies based on those discussions and comments received:
1. Instream Flow
Study: Two additional transects were
added to Study Site 4 (immediately below the drop structure). Calibration flows will be taken at
approximately 32 cfs, 15 - 17 cfs, and 3 - 5 cfs as measured at the drop
structure.
2. Anadromous
Spawner Surveys: Spawner surveys will
be conducted, beginning in August and continuing throughout the Chinook, coho,
and steelhead spawning season. Surveys
would extend from the mouth of Lake Creek to the chute at RM 1.03 on every
survey; other surveys would periodically extend to the barrier at RM 2.0.
3. Preference
curve verification: Spawning curve data
will be collected opportunistically during surveys if spawners are observed
during surveys. Preference curve data
will be collected on those fish observed during snorkeling surveys at a variety
of flows and areas of Lake Creek.
Information at the IFIM study sites at the different calibration flows
will be collected as practicable.
4. Target
species: Lower Lake Creek target
species are Chinook, coho, cutthroat trout and potentially other native species
that may be present. Target species
above the barriers is rainbow trout.
5.
Amphibians: Currently selected
transects will be evaluated to determine if some would be appropriate for
modeling. EES Consulting will provide
examples of preference curves for tailed frogs and Pacific giant salamanders as
developed in Oregon.
6. Potential
entrainment study: Provided permission
is secured from WDFW via Scientific Collectors Permit, the potential for the
project to entrain fish at the intake will be examined.
7. Potential
electrofishing study. Provided
permission is secured from WDFW via Scientific Collectors Permit, electroshocking will be conducted above the
barriers to establish relative distribution and abundance of rainbow trout and
other species that might be present.
8. Snorkeling
surveys: Absent Scientific Collectors
Permit, Lake Creek will be snorkeled at various study sites to determine
species presence, distribution and relative abundance.
9. Hydrology
Data: The hydrology data will be
further refined to reflect analysis requests from Dr. Hal Beecher and the U.S.
Forest Service.

have any questions, please contact me.
