Castile
Falls Fishway
Castile Falls, a
severe natural obstruction in the upper Klickitat River gorge consisting of multiple cascades and waterfalls,
was an historic impediment to the upstream migration of the majority
of anadromous fish into the upper Klickitat watershed. More recent measurement indicate Castile Falls are a series of eleven natural falls with a vertical drop of 108 feet over 0.67 miles.
Fishways were constructed in the late 1950s with Mitchell Act funds to provide anadromous access to approximately 33 miles of spring Chinook and 55 miles of steelhead habitat above the falls.
Design flaws and improper maintenance
contributed to the failure of the first attempt to provide passage over
the falls. Plan view drawing depicts entire series of falls with fishways that were constructed (from 1960s) and original 3D design drawings from late ’50s-’60s show the attempt to bypass 3000’of rock
for fish passage facilities.
They consist of three different fishways, located between river miles 64.0 and 64.7.
Falls Number 2, 3, and 6 were not considered fish blockages, so no correction was undertaken. The remaining falls, Number 1, 4, 5, 7, 8, 9, 10, and 11, all had improvements made.
Recently, the Castile Falls Fishway was renovated to bring
it into compliance with NOAA Fisheries' fish passage standards and facilitate
anadromous fish passage to habitats in the upper subbasin. From 2003-2005,
work was completed on the two fishway tunnels within the Castile Falls
complex. Improvements
to were approved by NOAA
Fisheries in 1999 under special appropriations to the Mitchell
Act to perform major maintenance activities after
the severe 1996 flood, which caused damage to several fishways in the Pacific Northwest. Construction activities were completed in summer 2005, opening access,
blocked for over 40 years, to over 50 miles of habitat in the upper
Klickitat to salmon and steelhead.
Design improvements
consist of conversion from a pool-weir style fishway to a vertical
slot fishway to allow passage over a wider range of river flow conditions
and to reduce maintenance needs. Project engineers and biologists have
measured improved flow, attraction flow and energy dissipation factor
(EDF) within the weir--all of which meet current criteria for fish passage.

Lyle
Falls Fishway and Adult Trap
Lyle Falls, also
known as Klickitat Falls No. 5, is located on the Klickitat River above
the confluence with the Columbia River at river mile (RM) 2.2. Klickitat
Falls No. 5 is approximately 150 feet in length and is bypassed by the
Lyle Falls fishway located on the right bank. Data
on adult fish using the fish ladder is collected daily.
The Washington State
Department of Fisheries (WSDF) began building the original reinforced
concrete fishway at Lyle Falls in 1949. By 1955, more formal facilities
were constructed. The facility is a vertical slot weir covered fishway,
with a three-port entrance pool. Included in the fishway are trapping
and sorting bays. A siphon was retrofitted above the fishway to provide
attraction water in the 1960's. Despite these efforts by the WDF, fish
passage at Lyle Falls met with only limited success. Bedload and debris
accumulations continually entrain material into the fishway, minimizing
exit pool depths and increasing operation and maintenance. The siphon
auxiliary water system designed to increase attraction flows at the
fishway entrance will not hold a charge due to bedload accumulation,
nor is it properly screened and configured to eliminate impingement
and entrainment of juvenile fish.
Passage through the Lyle Falls fishway can become difficult during low flow
conditions. At low flows, minimal water passes through the fishway,
whose exit channel is often shallow with exposed bedload, resulting
in fish reluctant to enter and exit the fishway. New fish passage technology,
improved since original construction, provides solutions to remedy problems
with the fishway and facilitate increased passage through a wider range
of flows, particularly during low flow conditions. Proper attraction
flows will increase ladder usage, improving escapement estimates
as fish pass PIT-tag
detectors. Increased passage through
a properly functioning fishway
will enable the collection of local broodstock for the YKFP integrated
and segregated hatchery programs. For more information about construction underway on the Lyle Falls fishway and adult fish trap as of spring 2010, click here.

Klickitat
Field Office
The Klickitat
Field Office (KFO) is the regional fishery office for the Yakima/Klickitat
Fisheries Project in the Klickitat subbasin and Southern
Ceded Area.
The
KFO is located in Wahkiacus, WA at RM 17 of the Klickitat River, near
the confluence of Swale Creek.
Staff at the KFO
includes Fishery Biologists, Habitat Biologists, Data Manager, Watershed
Planner, and habitat and fisheries technicians.
Meet
the staff. (Coming soon.)

Proposed
Facilities
Wahkiacus
Hatchery Acclimation Facility (WHAF)
As identified in
the Draft Klickitat Anadromous Fishery
Master Plan (KMP), transferring U.S.
v. Oregon production stocks (coho and fall Chinook) to the WHAF
accomplishes two primary objectives:
- it frees up critical
water and space at the Klickitat Hatchery, ensuring that optimal rearing
densities and protocols (YKFP and Hatchery
Scientific Review Group [HSRG] guidelines) are met for the two
endemic stocks (Klickitat spring Chinook and Klickitat summer steelhead)
- transferring
coho and fall Chinook production 26 miles downriver minimizes the
impacts of large-scale hatchery releases on wild spring Chinook and
steelhead rearing between the two facilities.
The 26 miles of
river between Klickitat Hatchery (RM 42.6) and WHAF (RM 17) lies within
the 3 EDT reaches (Lower Klickitat, Middle Klickitat and Upper Middle
Klickitat). EDT model output generated from physical habitat surveys
identify these reaches as having the highest potential for restoration
and preservation in the subbasin. Annual steelhead spawner surveys indicate
that 60% of the mainstem spawning occurs in these reaches.
Additionally, release
of well-acclimated coho and fall Chinook from WHAF imprinted to the
local groundwater signature will concentrate returns to the immediate
proximity of the facility, where concentrated harvest can occur, as natural production of coho and fall Chinook is not a program objective.
Castile
Falls Adult Enumeration Facility (CFEF)
The Castile Falls
Enumeration Facility (CFEF) will provide the ability to enumerate escapement
into the upper Klickitat subbasin, and assess recent improvements to
the Castile Falls Fishway. A counting station will be placed in the
upper CFEF. This structure will be installed at the fishway exit of
the Castile Falls 10/11 Fishway tunnel and will include video monitoring
and PIT-tag detection capabilities, as well as the ability to trap salmon
and steelhead for biological and DNA assessment and brood stock collection. The enumeration facility
will allow fisheries managers to:
- determine escapement
of Klickitat spring Chinook, summer steelhead and Pacific lamprey into headwater habitats
- assess stock
status and future trends as needed to calculate natural production
and adult-to-adult return rates, and to refine EDT and run forecasting
models used to guide integrated and conservation hatchery programs and
set harvest objectives
- conduct video
monitoring to gain critical biological data such as species, run timing,
size, and sex ratio of returning adults; and
- collect age and
DNA information on returning adults.
- assist with effectiveness monitoring of habitat restoration projects.

Bonneville
Power Administration (BPA) has finalized the Environmental Impact Statement for the Lyle Falls Fish Passage Project on the lower Klickitat River in Klickitat
County, Washington. The Final EIS consists of changes to the Draft EIS, copies of written comments, responses to these comments and a Record of Decision recommending moving forward with construction, as well as a detailed plan to mitigate for construction impacts.The
proposed action would modify the existing fishway and be designed to
safely and more effectively allow adult fish to move through the existing
Lyle Falls into spawning areas of the upper reaches of the Klickitat
River. The project would facilitate collection of fish for broodstock
purposes and monitoring of biological information for future fishery
management. Improvements would include reconstructing and lengthening
the fishway and trash racks, upgrading the adult trapping facility,
and adding a Passive Integrated Transponder (PIT)
tag detectors.
