channel braiding and large frequency of LWD in the lower 2 km. create excellent

lakes on mainstem and tributary (Tom Browne Creek) promote stability and likely

HABITAT
RESTORATION TO DATE - Extensive
FOC spawning channel complex is located near the Tom Browne Creek confluence (water
is drawn from Tom Browne Lake via intake structure).
SPECIAL
HABITAT PROTECTION REQUIREMENTS - Limit
headwater logging activities to minimize deleterious impacts on the stream.
- Preservation
of existing habitat is of paramount importance.
STEELHEAD
OBJECTIVES AND STRATEGIES - Consider
protection of adult steelhead with seasonal sportfishing closures.
- Review
operation of weirs at the outlet of Tom Browne and Glendale lakes to ensure minimum
flow releases are met in lowest reaches. All reaches above Tom Browne confluence
are sustained by Glendale Lake.
- A
specific anadromous trout/char survey should be undertaken.
NOTES:
Very large abundances of searun cutthroat trout are identified annually in
steelhead escapement surveys. A biophysical inventory/habitat capability assessment
was completed by FOC before development of the pink salmon spawning channels in
the 1980s but the focus was primarily on pink salmon and how they were impacted
by severe winter storms. Addition of inorganic nutrients is likely not needed
due to presence of large pink salmon runs, enhanced with FOC spawning channel
development. The
mainland coast streams appeared to fair better than east coast Vancouver Island
streams in the period 1997 through 2000. This was possibly due to the greater
proportion of ocean age 3 maiden spawners and geographic location on the east
side of Johnstone Strait. Assessments in 2000, 2001 and 2002 showed precipitous
declines in adult returns placing many stocks in the Conservation / special concern
zones. top |

HABITAT
RESTORATION TO DATE - No

SPECIAL
HABITAT PROTECTION REQUIREMENTS - Improve

STEELHEAD
OBJECTIVES AND STRATEGIES - Conduct
a biophysical inventory/habitat capability assessment. (The short anadromous length
likely has two reaches both with significant steelhead value.)
- Investigate
whether inorganic nutrient addition to increase primary production may be a viable
recovery option.
- Determine
feasibility of side-channels or over-wintering alcoves for improving juvenile
steelhead and coho survivals.
NOTES:
Recent interest in guided angling on this stream has waned with the collapse
of these stocks although a sportfishing closure may be considered due to the accessible
nature of the lower river. The
mainland coast streams appeared to fair better than east coast Vancouver Island
streams in the period 1997 through 2000 possibly due to a greater proportion of
ocean age 3 maiden spawners and geographic location on the east side of Johnstone

STEELHEAD
OBJECTIVES AND STRATEGIES - Conduct
a biophysical inventory/habitat capability assessment including Kippan Creek.
NOTES:
Inorganic nutrient addition may be considered, although watershed size/base
flows may make this option impractical for the mainstem below Kippan Creek (too
expensive). A biophysical assessment of Kippan Creek may show this major tributary
to be an excellent candidate for nutrient addition. The
mainland coast streams appeared to fair better than east coast Vancouver Island
streams in the period 1997 through 2000 possibly due to a higher proportion of
maiden ocean age 3 spawners and geographic location on the east side of Johnstone
Strait. Assessments in 2000, 2001 and 2002 showed precipitous declines in adult

Surveys in the fall of 2001, completed to identify potential encroachment
by Atlantic salmon, showed very large numbers of cutthroat trout and Dolly Varden
char in the lower 8km of this river. The
mainland coast streams appeared to fair better than east coast Vancouver Island

RESTORATION TO DATE - An
extensive semi-natural side channel is located downstream of the Elbow Creek confluence
on the rivers west bank. This unmanned spawning channel annually produces several
hundred thousand pink salmon but has produced as many as 800,000 pink salmon in
recent years.
-
The Twin Falls barrier was bypassed successfully in 1979 with a concrete fishway
increasing anadromous length from 2.7 to 22.0 km.
SPECIAL
HABITAT PROTECTION REQUIREMENTS - Improve
logging practices throughout watershed to minimize fish habitat impacts.
STEELHEAD
OBJECTIVES AND STRATEGIES - Monitor
encroachment of Atlantic salmon into this watershed from nearby fish farms.
-
Conduct a biophysical inventory/habitat capability assessment.
-
Consider as potential candidate for inorganic stream enrichment following water
chemistry monitoring
-
Monitor steelhead catch and effort, consider partial or complete sportfishing
closure of stream.
NOTES:
Mainstem lakes, overall anadromous length and the large population of pink
salmon should provide some measure of resiliency for this stock although it appears
to have suffered the most dramatic decline of all of the mainland coast index
streams. The
mainland coast streams appeared to fair better than east coast Vancouver Island
streams in the period 1997 through 2000 possibly due to maiden spawner age structure
(i.e., greater proportion of ocean age 3 adults) and geographic location on the
east side of Johnstone Strait. However, spring snorkel surveys in 2000, 2001 and
2002 showed precipitous declines in adult returns placing many stocks in the Conservation
/ special concern zones. top |
