Der Gulkana River ist ein etwa 95 Kilometer langer rechter Nebenfluss des Copper River im Süden des US-Bundesstaats Alaska.
Verlauf
Der Gulkana River bildet fünf Kilometer südlich von Paxson den Abfluss des Summit Lakes. Er fließt in südlicher Richtung. Dabei durchfließt er den Paxson Lake und mündet südlich von Gulkana in den Copper River. Der Richardson Highway und die Trans-Alaska-Pipeline verlaufen über weite Strecken parallel zum Fluss.
Name
Der Name „Gulkana“ hat seinen Ursprung in der Bezeichnung der Ureinwohner Alaskas für den Fluss. Oscar Rohn notierte den Namen 1899 als „Kulkana“. Die heutige Schreibweise wurde von W. R. Abercrombie, einem Hauptmann der United States Army, eingeführt. Henry Tureman Allen hatte 1885 die Bezeichnung „Tonkina“ gemeldet.
Naturschutz
Einige Teile des Gulkana River wurden 1980 durch den Alaska National Interest Lands Conservation Act als National Wild and Scenic River unter die Verwaltung des Bureau of Land Management gestellt.[4][5]

The Gulkana is one of the most popular sportfishing rivers in Alaska, providing rich habitat for rainbow trout, arctic grayling, king salmon, red salmon, whitefish, longnose suckers, and lamprey. A poplular river for fisherman and boaters in the summer, this river has also played an important role in the lives of the Ahtna, providing access to subsistence resoucres throughout history and pre-history. During winter months the frozen Gulkana River was historically used as an important travel route from the Copper River to the Tangle Lakes and what is now known as the Denali Highway area.
The Gulkana River Watershed drains approximately 2,140 square miles of Southcentral Alaska. The river begins in the Alaska Range near Summit Lake and flows south into the Copper River, eventually draining into Prince William Sound. Several hundred lakes and ponds are scattered throughout the spruce-dominated forest of the Gulkana River Watershed, providing abundant nesting areas for trumpeter swans and waterfowl.
