TWENTY-SEVENTH BIENNIAL REPORT. 55 



water to operate the fisliways properly and maintain the tisli below their 

 dams. The amount of water that is necessary to comply with the fish- 

 way law, during the minimum flow of water in the late summer and fall 

 is not great enough to work any damage to the power companies. 



During the spring and late fall when the fish are ascending the 

 streams to spawn there is ample water for all purposes. All that is 

 required during the minimum flow is that enough water be allowed to 

 pass through the fishway, culvert, over or around the dams to maintain 

 fish life below them. 



Following is a list of fishways surveyed and inspected for repairs or 

 alteration hy inspectors since our la.st report.
