KLAMATHON SALMON EGG-COLLECTING STATION 



This station was ('stal)lislu'(l in ll'lO lor tlic ]uif|)oso of collecting 

 salmon i'<r<^s for (list rihiit ion in llic Klamath a?Ml Sacramento rivers. 

 The station is subject to seasonal conditions pi-obably more than any 

 other station on the coast. Durinj]: a season of early rainfall and falling 

 temperatures, the salmon ascend the river in larire Tiumbers; during 

 seasons of warm and dry weather in the fall the salmon run in the 

 upper reaches of the Klamath Kiver is light. As far as our observa- 

 tions are concerned and knowing that the run of salmon is not constant, 

 but in the upjicr reaches of the river is governed by seasonal conditions, 

 we are not ])i-(>])ared to state whether the run of fish has been reduced 

 by excessive fishing in the ocean areas before entering the river or not. 



A comprehensive survey of the river covering a period of years \\i\\, 

 in our judgment, be necessary before determining whether the I'un has 

 materially decreased or not. The movements in the upper reaches of 

 the river fluctuated in the same manner some twenty years ago a.s it 

 has during the last ten years. 



Following is a table of the numlier of eggs collected from the Chinook 

 salmon, which clearlx' indicates the fluctuatinu- num})ers of salmon in 

 the runs as they reach the traps at the Klamathon Station :

All the salmon eggs collected durin<x th(> last three years have been 

 hatched at Fail Creek station and the resulting fingerlings have been 

 returned to the river. Our opinion, based on over thirty j^ears' study 

 of the fishing conditions in the Klamath Kiver, is that when seasonal 

 conditions change and a period of normal rain and snowfall prevails, 

 the salmon will reach the Klamathon Station in numbers that will 

 average the same as they have for tlie last twenty years. The water 

 is held back in the Klamath Lake by the power company during the 

 dry season and has its etfect on the salmon run as is definitely proven 

 by the movements of the salmon. 



The Klamath, like all rivers in this state, is heavily fished, but the 

 number of salmon taken, except in the cannery, has no effect on the 

 run on the upper reaches of the river. The cannery, in our judgment, 

 takes only a small percentage of the run as the ocean fishing no doubt 

 is of greater consequence than the operation of the cannery on the 

 salmon that ascend the river.
