(Editor's note: Thii it the
10th in a series of articles
on the Rogue fishery and
its ' management. Today's
article is a general discus
sion of the need to pre
serve the natural character
istics of streams and lakes
to maintain adequate fish
ing. The program to correct
some of the more serious
losses of fish is outlined.)
Cole Klverl
By COLE M. RIVERS
Fisheries Agent
State Game Commission
Stream protection is one of
the most important phases of
fishcrv management work.
The most suc
cessfully prov
en method for
main tnining
fish popula
tions, particu
larly s a lmon
and stcclhead,
Is to protect
the natural
characteristics
of our streams
and give Mother Nature a
chance to do her job well.
Hatcheries can be used to
solve isolated problems, but
the most effective method to
preserve and restore fish runs
is to protect the habitat and
let the fish do the Job for
themselves.
Poorly designed and care
lessly constructed roads from
the fish management stand
point can damage streams so
that many years may be re
quired for recovery. Some
streams are already so badly
damaged that they may never
recover. Much progress has
been made in the past decade
to encourage road building
agencies to modify their de
signs for the protection of
streams and fish life.
Destroy Habitat
Logging operations often
destroy many miles of fish
habitat In streams. The dam
age is commonly caused by
skidding logs into the chan
nel, stripping the banks of
valuable cover, and leaving
debris from which jams can
be formed.
Abandoned, exposed soils
may erode and, as a result,
fish eggs and aquatic fish
foods in the gravel are smoth
ered. Abusive disturbance of
cover often causes changes in
the pattern of runoff so that
the streams suffer from scour
ing floods in the winter and
dry beds in the summer.
Not many years ago, little
was known on just how to
prevent damages to streams
by logging. Trial and error
methods were studied by co
operating agencies, such as
the private timber companies,
forest service, soil conserva
tion service, and the game
commission. Improved logging
and road building techniques
were found to protect water,
soil, and cover.
Good Management
Private landowners are us
ually Interested in the pro
tection of their own lands.
They, too, are learning Hint
stream protection practices
needed for fish follow the
principles of good land man
agement. Fishery people are attempt
ing to secure the cooperation
of private agences engaged in
land-use practices to protect
the streams and watershed
More Important Is the need
to Inform the general public
which methods are damaging
and which procedures are
beneficial.
Inventory of 'log jams and
ladders, building fi.sli passage
at dams, recommending solu
tions to problems at bridges,
culvrts and Irrigation feH-
ities arc other routine rvipun
nihilities of fish munasxrs.
Method Sound .
Wheiwi method knind
to prevent the extensive lotses
of downstream migrant eleel
head and salmon in irrigation
ditches, the game ciommfelon
constructed a plant at Control
Point to Oevelop and ii'O'ui
facture the Oregon rotary fish
screen. Decause of mQtQl
shortages through World Var
II, the program was not start
ed on a large scale until llk5.
This Is now one of the most
tlmc-consumlnOmd expensive
programs the game commis
sion undertakes. Yet it ranks
high In Importanc for the
protolonQof salmon and
ateelhcad. A state law re
quires that all dltehrs and di
versions under eight fr0 in
width be scrcennd aiW nifti
talncd by the commission. On
largrr diversions, this respon
sibility lies with the build

LOG JAM Ihis shows a typical log jam that was formed represent only a part of the damage to tributaries and
by tinordeily logging practices. These jams block runs of fish life, according to the Oregon game commission,
steelhead and salmon from valuable spawning areas, and
Rogue watershed at one lime.
In 1960, 156 screene wore
being used and maintained.
Worth Expenditure
The game commission feels
that this ' screening program
is well worth the expenditure
involved. As many as 27,000
wild migrants have been
counted from one screen on a
tributary. Larger screens
which divert migrants from
ditches off the main channels
of the Rogue and Applcgate
divert many more in a season.
A 1950 study showed that
the numbers of fish saved
from all screened ditches in
the Rogue system that year
represented more fish than 10
of the Butle Falls hatchery.
More Important, these were
rugged, wild salmon and stccl
head that are known to be
maintaining the Rogue river
stocks.
Because of adverse flow
conditions, not oil screens can
save 100 per cent of the mi
grants in a ditch. Many
changes are being made every
year to eliminate the escape
ment of fish through and
around screens and to try to
attain 100 per cent efficiency.
In the past, fish ladders
were constructed along a
common pattern. When It was
realized that most of these
old-type structures provided
fish passage at only one stage
of water, biologists, engineers
and hydrologists combined
their knowledge to design lad
ders that could be used by
fish at all stages of flow. The
joint efforts of these special
ists have also made It pos
sible to remove fish from
large volumes of water such
as from canals and forcbays
above turbine Intakes.
Laws Inadequate
Generally, the laws which
protect fishery habitat are In
adequate In Oregon. The law
prohibits trees, logs, brush
and drift placed in or nrar a
stream without "forthwith re
moving the nunc" is a val
uable tool for controlling
damage created by logging
There is no strong legisla
tion to control silt loads. Laws
do not exist to control the
removal of gravel from val
uable stream beds, but some
oiwralorj. arc showing excel
lent cooperation with the
same commission by s'pi't
inc llieir borrow area from
the main stream flow with

Lung Cancer
Tissue Grown
In Laboratory
San Francisco - (IIP1I- A Uni
versity of California scientist
has succeeded In growing hu
man lung cancer tissue in the
laboratory, the American Can
cer Society has reported.
The scientist is Dr. Redla
Caillcau of the Medical Cen
ter's Cancer Research Insti
tute. She has been able to grow
lung cancer cells in flasks for
the past two years, enabling
her to study the physical and
chemical behavior of lung
cancer under controlled con
ditions. Pationt SHU Alive
The cancerous tissue which
provided the cells was re
moved from a portion of lung
from 53-yoar-nlrt barber in
January, 11)5(1. The patient
still is alive and in good
health, the society said.
The original (issue, about
the sire of a walnut, was cut
into small hits and grown in
covered dishes. Most of the
pieces, thv society said, were
made up of groups of delicate
strands.
