Iliamna Lake or Lake Iliamna is a lake in southwest Alaska, at the north end of the Alaska Peninsula, between Kvichak Bay and Cook Inlet, about 100 miles (160 km) west of Seldovia, Alaska.[1]
It is the largest lake in Alaska, second largest lake in the United States, and eighth largest in North America (Lake Michigan is largest, all other Great Lakes are shared with Canada. It is eighth largest on continent of North America) covering about 2,600 km² (1,000 sq. miles). The lake is 77 miles (124 km) long and up to 22 miles (35 km) wide, with a maximum depth of 988 feet (301 m). Through the Kvichak River, its waters drain into Bristol Bay.[3]
History
Name
The lake is marked as 'Oz[ero] Bol[shoy] Ilyamna' (Big Ilyamna Lake) on the Russian Hydrographical Department's Chart 1455, published in 1852. On an earlier Russian map, from 1802, the lake was named 'Oz[ero] Shelekhovo' (Lake Shelekov) after Russian explorer Grigory Shelekhov. According to G.C. Martin, of the United States Geological Survey, Iliamna is said to be "the name of a mythical great blackfish supposed to inhabit this lake, which bites holes in the bidarkas of bad natives."[1]
The name Iliamna is derived from the Inland Dena'ina Athabascan name Nila Vena, which means island's lake.[4]
Economy
Williamsport-Pile Bay Road portage
Originally constructed by the Alaska Road Commission during the mid 1930s, the Williamsport-Pile Bay Road is a utility-class road maintained by the Alaska Department of Transportation & Public Facilities. Connecting Pile Bay on the lake's northeast side with Williamsport, a tiny settlement on the Iliamna Bay of Cook Inlet (about 100 miles (160 km) southwest of Homer), the road is 15.5 miles (24.9 km) long and one lane wide with four bridges. The Williamsport-Pile Bay Road is maintained as a gravel utility road for the purpose of hauling boats and freight, and is not intended for general purpose use. The road allows boats small enough to be hauled across the road's bridges an opportunity to portage from Cook Inlet to Bristol Bay, saving a trip on the open ocean which involves traveling around the Alaska Peninsula. For this and other reasons, the road is also believed to significantly reduce fuel costs for the Lake Iliamna and Bristol Bay regions.

Wildlife
Iliamna Lake is noted for its sport fishing. The three primary targets of anglers in the lake are trout, salmon, and grayling. August through September is prime time for catching fat rainbow trout, some of which exceed 28 inches long. The Kvichak River Policy (the drainage of Lake Iliamna) is catch and release on trout (and all other native fish), but not on salmon. Sockeye (Red) and Chinook (King) Salmon are consistently found in the lake and are open to harvest under Alaska Department of Fish and Game Regulations. Lake Iliamna also has one of few populations of freshwater seals in the world.[5] It also serves as a nursery for the largest Red Salmon run in the world. Red salmon spend half of their 5 year lifespan in fresh water. This is longer than any other species of salmon.
Monster
Local residents have a number of stories about the alleged Iliamna Lake Monster, an aquatic creature much like the rumored Loch Ness Monster.[6] Speculation exists that reported sightings may be an undocumented population of white sturgeon. If true, this would be the most northerly population known to exist, just a few hundred miles from the Arctic Circle. Jeremy Wade, presenter of Animal Planet's River Monsters is among those who speculate these sightings of a reputed "monster" is a White Sturgeon. Many others believe that it is a Pacific Sleeper Shark
