REPORT OF THE FISH AND GAME COMMISSION. 39 
fish can be increased and improved by the establishing of a hatchery 
on the Klamath River below the Copco dam where several hundred 
thousand fry can be hatched each season and planted in the upper 
reaches of the river above the dam. In the large body of water formed 
by the Copeo dam the trout will thrive and furnish excellent fishing 
on all the upper reaches of the river. 
Under the provisions of the law passed by the last legislature, when- 
ever a dam or other obstruction is placed in a river or stream that, in 
ihe judgment of the Fish and Game Commission, is too high for the 
successful operation of a fishway, or for other reasons it is deemed best 
to establish a hatchery below the dam for the propagation of any 
species of fish that may be interfered with by the construction of the 
dam, the owners of the dam must construct and equip a hatchery for 
the purpose of propagating fish for the river and turn it over to the 
state for operation. This is the policy that the Federal Government is 
taking in Alaska, and it is the law in the State of Washington. Last 
year five hatcheries were built and equipped in Washington by the 
owners of large dams and turned over to the state. Our commission 
is frying to follow the same course on the Klamath River, as it is the 
only practical way of insuring a good supply of trout in the upper 
reaches of the Klamath River. 
The trout fry will not to any extent descend the river or pass through 
the tubes furnishing water to the power plant, as it is well known that 
the young of the trout do not inhabit the deeper water of any lake or 
pool, but prefer the shallow water and the current that they continually 
head against up stream. 
The salmon fry, on the other hand, on their migration to the sea 
move slowly backward with the current and are easily drawn in to any 
pipe or over the crest of a dam or waterfall, while the instincts of the 
trout fry cause them to avoid all such places. 
All arrangements are now complete for the construction of a large, 
modern hatchery on Fall Creek this summer. This hatchery will be 
used to propagate salmon as well as supply the upper reaches of the 
Klamath River with an ample number of trout fry to insure as good, 
if not better, fishing in that section than was had before the dam was 
built. The California and Oregon Power Company, complying 
with the provisions of the law, will establish this hatchery free 
of all expense to the state, turning it over to the commission for. 
operation. 
The racks and traps will be located at Klamathon, where. successful 
egg-collecting operations have been carried on by the California Fish 
and Game Commission and the United States Bureau of Fisheries for 
several years past, and the hatchery on Fall Creek, 12 miles from the
