Granlees Dam and four flashboard dams along the Lower Cosumnes River have impeded the passage of upstream migrating Chinook salmon. In 1998 the FFC began a program to develop and impement fish passage solutions to each of these sites. To date the FFC has completely rebuilt the south ladder at Granlees Dam, constructed a box culvert at a low flow crossing, and improved passage at three flashboard dam foundations by manipulating the rip rap approach and installing concrete curbs to focus the flows at the structures. The FFC currently has funds to install a boulder weir at the remaining flashboard dam and to rebuild the north ladder at Granlees Dam in the summer of 2010. These actions will eliminate the remaining barriers on the Cosumnes River.
