The Karluk River is located on Kodiak Island in Alaska. It flows approximately 30 miles from the Karluk Lake to the Karluk Lagoon, where it empties into the Pacific Ocean. The river is known for its rich ecosystem, supporting various fish species, including salmon, which attract both wildlife and anglers. The river's watershed is part of the Kodiak National Wildlife Refuge, providing habitat for diverse wildlife such as bears and eagles. The area is also significant for its cultural history, as it has been inhabited by the Alutiiq people for thousands of years, who relied on its resources for sustenance.
