fish ladder

Hundreds of millions of dollars are spent each year on improving fish ladders, hatchery programs, trucking and barging fish to get around the dam system, but it hasn’t been enough.

For fish swimming upstream, fish ladders on the side of the dams have been repeatedly improved to allow salmon migrating from the ocean to propel themselves from concrete eddy to concrete eddy upstream.

There's more good water—two miles of it—to the east, and all it needed was a fish-ladder around Scaur Falls.
