The Alagnak River runs for 64 miles and is a tributary of the Kvichak River. The River begins where the outflow waters of Kukaklek Lake spill over and it ends when it empties into the Kvichak River. The Alagnak River begins inside of the Katmai National Park and Preserve.
The river is dynamic and somewhat fast. As it covers various terrain it expands and contracts, but all along its course it offers outstanding fishing. It can be a narrow river with a deep channel or a shallow river suitable for wading.
