<br />001541 <br /> <br />Fish Ladder <br /> <br />Design <br /> <br />Designs for the ladder would be reviewed to ensure compatibility with plans for the hydroelectric <br />power plant. The power plant and ladder would be built on the right bank of the riverI. <br />Conceptual designs for development of the site show the channel of the ladder surrounding the <br />outside wall of the power plant intake (see Figure 2). The ladder would consist of a 200- to 250- <br />foot-long concrete channel, 6-feet wide and 8- to 10- feet deep. About 25 cfs of streamflow <br />would be diverted into the channel for the ladder. The upstream entrance to the chamlel will <br />have a trash rack to prevent debris from entering. Baffles (vertically placed plates) would divide <br />the channel into a series of small pools~ fish would swim from pool to pool through openings in <br />each baffle. The baffles would be placed at appropriate intervals to keep flows at velocities that <br />native fish can swim against. The fish passage site would be fenced with a 6-foot-high fence for <br />facility and public safety; a bridge over the fish ladder channel would permit vehicle access to the <br />hydropower plant. <br /> <br /> <br />~ <br />~ <br />~~ <br /> <br />~1'6 <br />O$)~+ <br /> <br />I <br />i <br /> <br />w <br />.....
