The concept of damming the river to generate hydroelectric power dates back to the 1940s, driven by the growing energy demands of Alaska's population center in Anchorage. This region, located roughly 100 miles north of Anchorage in the Matanuska-Susitna Borough, encompasses a vast and largely untouched wilderness.
