The new fishway at Sutter Butte dam on the Feather River. Phofograph fay J. A. Aplin, July, 1952. Work on the new fishway was begun in October of 1950. Construc- tion was difficult, as the river bed at this location is composed of Large cobbles to a considerable depth. These shifting rocks made the building of a cofferdam around the foundation area slow and the up- welling of water from below hard to stop. Exceptionally high water within a month after work was started destroyed the cofferdam and washed away a number of the concrete forms. Work had to be abandoned until the lowering of the water in The summer of 1951. On October 24, 1951, a flow of water was started through the fishway. although work was still going on, and within a few minutes upstream migrating salmon were seen entering it. Within an hour several dozen fish had passed through the ladder and others were coming in an almost continuous procession. This was particularly encouraging as the tisli had to jump over a temporary wall which had only six inches of water flowing over it. This wall was removed a few days later and access into the fishway was much easier. The project was officially completed on November 8, 1951, at a cost of $45, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
