Hydropower plants install _____________ ladders to help fish swim upstream to reproduce. Some hydropower plants have fish

These ladders install with sturdy bolts, so a standard socket wrench set should work. Take care that you choose either a metric or regular set depending on where your ladder bolts were made.
Most dams have side-runs, fish ladders, tubes or tunnels for salmon to move past the dam. The problem remains that the dam may have flooded the salmon's original breeding grounds. Most dam agencies try to maintain some of the salmon's original breeding habitat. If all of this habitat is destroyed, then those salmon can not reproduce.
Measuring Tape, Wrench, Power/Hammer drill with wood drill/stone bits, Ladders(depending upon the height you need to install) are the tools you need to install a retractable awning.
Hydroelectric power has been touted as the 'environmentally clean, renewable source of power.' This is subject to debate, as hydroelectric dams use turbines to generate electricity, and these turbines are spun by shafts which have blades on them. Fish which get caught in the high-pressure streams of water directed at the turbine blades usually do not survive the encounter with the blades. Also, the impoundments, or lakes, behind hydroelectric dams slow the speed of the river so much that many young fish do not survive the long swim to the ocean, where food is plentiful in comparison to rivers. Of course, dams present a complete barrior to upstream migration, unless fish ladders are in place, and even fish ladders are not 100 percent effective, as many fish are unable to locate the ladders. Salmon populations upstream of Grand Coulee Dam, which does not have fish ladders, disappeared, except for the freshwater varieties.

You want ladders that will not conduct electricity. Aluminum ladders are not a good idea. Fiberglass ladders are best for working around power cables.
