Monster legend

Local residents have a number of stories about the alleged Lake Iliamna monster, an unknown aquatic creature. There is speculation that reported sightings may be an undocumented population of white sturgeon. If so, this would be the northernmost known population, just a few hundred miles from the Arctic Circle. Jeremy Wade, host of Animal Planet's River Monsters, is among those who speculate that these sightings of an alleged "monster" are a white sturgeon. Others believe it is a Pacific sleeper shark. This is confirmed by a 2012 YouTube video showing a smaller Pacific sleeper shark in Lake Iliamna. There were several new sightings in 2017. The Anchorage Daily News once offered a price of $ 100,000 for concrete evidence of their existence.


Location of Iliamna in Alaska


The lake is identified as "Oz [ero] Bol [shoy] Ilyamna" (Great Lake Ilyamna) on the 1455 map of the Russian Hydrographic Department published in 1852. On an earlier Russian map, the lake was named "Oz" from 1802 [ero] Shelekhovo '(Lake Shelekov) after the Russian explorer Grigory Shelekhov. According to GC Martin of the United States Geological Survey, Iliamna is said to be "the name of a mythical large black fish that is believed to inhabit this lake that bites holes in the bidarkas of evil natives."

The name Iliamna is derived from the inland Dena'ina Athabascan name Exit Nila Vena, what island lake means.


Williamsport-Pile Bay Road Portage

Williamsport-Pile Bay Road was originally built by the Alaska Road Commission in the mid-1930s and is a utility-grade road maintained by the Alaska Department of Transportation & Public Facilities. The road connects Pile Bay on the northeast side of the lake with Williamsport, a tiny settlement on the Iliamna Bay of Cook Inlet (about 160 km southwest of Homer). It is 15 miles long and one lane wide with four bridges. Williamsport-Pile Bay Road is maintained as a gravel road for the transport of boats and cargo and is not for general use. The road allowed boats small enough to be towed across the road bridges at an opportunity to portage from Cook Inlet to Bristol Bay, saving a voyage on the open seas that includes traveling around the Alaska Peninsula. For this and other reasons, the road is believed to reduce fuel costs significantly for the Lake Iliamna and Bristol Bay regions.

Populated places

The villages of Iliamna, Newhalen, Kokhanok, Pedro Bay, Pope-Vannoy Landing and Igiugig are on the shores of Lake Iliamna.

Flora and fauna

Lake Iliamna is known for its sport fishing. The three main fishing destinations in the lake are trout, salmon and grayling. August through September is the best time to catch fat rainbow trout, some of which are longer than 30 cm. The Kvichak River Policy (the drainage of Lake Iliamna) provides for the catching and releasing of trout (and all other native fish), but not salmon. Sockeye salmon and red (king) wax are regularly found in the lake and can be harvested according to the regulations of the Alaska Department of Fish and Game Regulations. Lake Iliamna also has one of the few populations of freshwater seals in the world. It also serves as a kindergarten for the world's largest sockeye salmon run. Red salmon spends half of its 5-year lifespan in fresh water. This is longer than any other type of salmon.
