Final Environmental Assessment — Chapter 2— Alternatives <br />into the channel for the ladder. The upstream entrance to the channel would have a trash <br />rack to prevent debris from entering the fish ladder. Baffles (vertically placed plates) <br />would divide the ladder into a series of small pools; fish would swim from pool to pool <br />through openings in each baffle. The baffles would be placed at appropriate intervals to <br />keep flows at velocities that native fish can swim against. The site would be fenced with <br />a 6 foot -high fence for facility and public safety.

Jacobson properties would be used along the right -bank <br />of the river to provide construction and maintenance access. <br />A fish trap to control upstream movement of nonnative fish was also considered in the <br />preliminary designs for the fish ladder. However, factors such as cost, site limitations, <br />and land ownership at the dam site may make it infeasible to include a fish trap at this <br />location. A fish trap was constructed at the Grand Valley Project Fish Passage located <br />about 5.3 miles upstream of the Price -Stubb Diversion Dam to prevent upstream <br />movements of nonnative fish above the Grand Valley Project Diversion Dam. <br />Reclamation also examined constructing a conventional fish ladder on the river -left bank <br />of the Price -Stubb Diversion Dam but determine the design to be cost prohibitive. <br />0 ' Hydro plant is not included in the proposed action and is shown for illustration purposes only. <br />LE <br />
