Some Northwest Indian tribes in the next 20 years want to achieve a long-held dream: restoring wild salmon runs above the giant Grand Coulee Dam. The construction of Grand Coulee in the 1930s blocked salmon runs that historically ran into the millions of fish each year, killing what had been a way of life for Indian tribes in the region. For decades, tribes were told it would be too expensive to try and restore the runs. But new technology has raised hopes among tribal members. A decision on whether to proceed with the initial study in this effort is expected this spring.
