Tustumena Lake stands as one of Alaska's most remarkable fishing destinations, sprawling across 73,000 acres to claim the title of the largest lake on the Kenai Peninsula and the eighth largest in all of Alaska. Located in southcentral Alaska within the Kenai National Wildlife Refuge near Kasilof, this pristine wilderness lake reaches an exceptional maximum depth of 950 feet, making it deeper than the neighboring Cook Inlet. The lake stretches 25 miles long and up to 6 miles wide, with its outlet forming the headwaters of the Kasilof River. Fed by Tustumena Glacier and several creeks, the lake's glacial influence gives it a distinctive silvery appearance that distinguishes it from clearer water bodies. Known by its Dena'ina name "Dusdu Bena" meaning "Peninsula Island Lake," Tustumena offers anglers an unparalleled opportunity to fish for diverse species in one of Alaska's most remote and scenic settings, surrounded by towering mountains and untouched wilderness.
