Matanuska-Susitna Borough · ADF&G Sport Fishery

The largest river system in southcentral Alaska — 313 miles from the Susitna Glacier in the Alaska Range to Cook Inlet. The Susitna drains an area larger than the state of West Virginia and supports all five species of Pacific salmon, with king and silver salmon as the primary sport targets. The river is the largest tributary system in the matanuska-Susitna valley and is the access route for nearly every fishing trip in the Talkeetna and Yentna river basins. Most sportfishing happens on the lower Susitna and its tributaries, accessible by jet boat from Talkeetna or Susitna Landing.
