Sheenjek River

The Sheenjek River sonar site is the northern most sonar site the Alaska Department of Fish and Game operates. The fall chum salmon ADF&G monitors at this site, swim extraordinary distances and seek out spring feed streams to spawn. Chum salmon destined for spawning grounds in the Sheenjek River first travel more than 1,000 miles up the Yukon and Porcupine and rivers. Sonar site estimates of Sheenjek fall chum salmon are used to manage Yukon River drainage fall chum salmon, which support both commercial and subsistence fisheries.
