The Kenai River boasts major runs of four Pacific salmon species: king, red, silver and pink; in addition to trophy sized rainbow trout and Dolly Varden. Kenai River kings, or Chinook salmon, are among the largest North Pacific salmon, often weighing from 50 to over 85 pounds. The abundant productivity of the Kenai River and variety of habitats enables the area to support large concentrations of bald eagles and many species of migratory waterfowl. Moose, caribou, wolves, bears and other wildlife also use the river system's resources. The area offers prime opportunities for fishing, boating, camping and wildlife observation.

The Kenai River Special Management Area (SMA) consists of more than 105 linear miles of rivers and lakes, including Kenai Lake, Skilak Lake, and the Kenai River from river mile 82 downstream to four miles above the river's mouth on Cook Inlet. Bing's Landing State Rec Area is adjacent to these waters, along with fifteen state park sub-units. Other Kenai River land is owned by cities, the borough and the federal government, as well as private and native lands. Please respect all property along the river.
