The Susitna is a huge glacial river that drains the indomitable Alaska Range. Denali looms on the horizon. One of America’s last great, wild, undammed rivers, it is home to large numbers of king, sockeye, pink, coho and chum salmon, which push through its heavy currents to spawn in its clear-water tributaries. The “Su” sees the fourth largest king salmon run in Alaska, producing hundreds of thousands of them each year.
The state of Alaska wants to build a 735-foot-high dam on the Susitna to generate electricity. It would be the nation’s second tallest. It’s not the first time the Su has been looked to as a potential source of hydropower. Studies done in the 1950s and ‘80s both explored the feasibility of damming the river. Both agreed that it didn’t make financial sense.
