FISH AND GAME COMMISSION 



REPORT OF THE BUREAU OF ENGINEERING 



By J. Spencer, Chief 



In the first portion of the biennium the limited personnel of the 

 bureau was very busy in preparing plans and carrying on the required 

 construction to fulfill the commission's extensive plan of additions and 

 improvements. Due to the United States defense program which was 

 later followed by the war and attendant difficulties as regards materials 

 there was a lessening of construction in the latter period. In addition 

 to this the bureau took care of the necessary work on fishways, fish screens 

 and other stream improvement projects. 



For the biennium there were 118 dams inspected to see what 

 adverse affect, if any, these dams had on the required free movement 

 of fish. Where it appeared that remedial measures were needed, the 

 owners of these dams or obstructions were contacted and alterations or 

 improvements were brought about. Ten fishways were repaired or 

 replaced, this being necessary as the structures had been damaged by 

 high waters or other causes. Where the dam was without a fishway and 

 one was needed to permit fish an uninterrupted passage a survey was 

 made and plans prepared for the installation of the required fishway by 

 the owner of the dam. As a result of these surveys and negotiations 

 eight new fishways were installed. 



The work of replacing fish screens in accordance with commission 

 policy continued to the summer of 1941, when 55 installations had been
