5:15 PM LOCAL TIMEIliamna Lake ranks as one of North America's largest lakes, covering approximately 8,100 km² (3,100 mi²) in southwest Alaska. Nestled in the Alaska Peninsula region, it lies at elevations near sea level and is fed by glacier- and river-origin inflows. The lake drains into the Kvichak and Nushagak rivers, which are known for robust sockeye salmon runs and support both commercial fishing and subsistence fisheries. Historically and ecologically significant, Iliamna is also a remote wilderness destination accessed mainly by floatplane and boat, serving as a base for fishing, wildlife viewing, and wilderness camping. The surrounding landscape includes alpine ridges, tundra, and shrubsteppe habitats—all prime areas for large salmon, bull trout, and nesting waterfowl.
