If there were no other justification for the existence of the Fish and 

 Game Commission it could well rely upon the results of its attempt to

Considerable progress in the installation of fishways and screens 

 has been made. Eighty-six suitable fishways have been constructed at 

 many places where fish have been unable to ascend streams because of 

 dams or some natural obstruction, and ninety-two other sites have been 

 surveyed. By the removal of large boulders and other natural obstruc- 

 tions the breeding grounds of fish have been greatly extended. In one 

 instance more than 100 miles of spawning grounds were added by the 

 removal of such an obstruction. 



Experience has shown that the largest canals can be screened and the 

 flow of water be undiminished. Even the work of cleaning has been
