70 FISH AND GAME COMMISSION 



the fishways installed. If changes have occurred which necessitate a 

 new survey, this is made, and work of installation resumed. 



There are many dams on the streams of this state that have not yet 

 been surveyed. The most important ones, of course, have received first 

 attention. 



In several instances where the orders of the Commission requiring 

 fish way installation have not been followed out the aid of the courts 

 has been sought. The legal department will no doubt report on these. 



The bureau is happy to state that, of the fishways installed during 

 the past two years, reports show these installations to be efficient. A 

 fishway installation of considerable importance was made by the Ander- 

 son-Cottonwood Irrigation District on the Sacramento River at Red- 

 ding. This dam had formed a barrier to migrating salmon and steel- 

 head for seven years and only a small number of fish had succeeded in 

 passing. A change in the plan came as the result of a harmonious con- 

 ference and construction of the fishway followed. Now the migrating 

 salmon and steelhead pass on upstream. An effective barrier to migrat- 

 ing fish can stop the run up that stream and in a few years make the 

 stream above practically barren of migrating fish life. The installation 

 of three fishways on dams on coast streams in Mendocino County opened 

 up a large area which had been closed for many years to spawning fish. 



In the latter part of 1926 much publicity was given the alleged satis- 

 factory working of a fishway over a dam 200 feet in height (planned 

 ultimate height 250 feet) on the Baker River at Concrete, Washington. 

 If the facts warranted the statements made, then a great advance had 

 been made in fishway construction. In addition the proponents of 

 hydro-electric development on the Klamath River might be encouraged 

 to attack the initiative measure passed by the people of California in 

 1924 which saved that river as a fish reserve. 



Mr. N. B. Scofield of the Bureau of Commercial Fisheries and the 

 writer inspected and studied the results of the operation of this fish 

 ladder and presented their views to the convention of the International 

 Pacific Salmon Investigation Federation, which met in Seattle, Decem- 

 ber, 1926. This body passed a resolution condemning the publicity as 

 presented to the public as not being warranted by the facts. It can not 

 be said, at this date, that the Baker River Dam fishway is a success. 



POLLUTION CONTROL OF THE PUBLIC WATERS 



The pollution work was added to the bureau in January, 1927, and 

 subsequent to that time each reported case of pollution has been checked 

 and remedial measures effected where conditions warranted. Bureau 

 action has not, however, been dependent on the reports received, in fact, 

 the greater portion of the activities have been initiated by the bureau. 

 It was found by a brief preliminary inspection that many cases of 

 pollution were occurring and the director was of the opinion that 

 greater good would be accomplished by working on each pollution prob- 

 lem as presented rather than any general survey of conditions. The 

 results attained will bear out that viewpoint. 



As in the other phases of bureau activities legal action is only resorted 

 to after other means fail to accomplish results. Where an industry or 

 individuals are polluting public waters, an effort is made to have it 

 remedied and reasonable time is given to effect the needed changes.
