Amakdedori Creek, Kamishak Bay

Amakdedori Creek, Kamishak Bay

by | Mar 25, 2020

Amakdedori Creek flows southeast for 10 miles (16 km) from the Aleutian Range to Kamishak Bay, about 26 miles (42 km) southwest of Augustine Island, and 95 miles (153 km) southwest of Homer, Alaska. The creek was named after a historical Alaska Native village called Amakdedori at the mouth of the creek that in 1905 consisted of two families occupying separate cabins. Amakdedori was also used as a seasonal camp by Lake Iliamna villagers who hunted beluga whales and gathered shellfish. An ancient portage trail connected Amakdedori with Lake Iliamna and was used as a trade route between coastal and interior bands of Yup’ik, Alutiiq, and Sugpiak.

The Pebble Mine is a proposed project to extract copper-gold molybdenum porphyry ore (Pebble Deposit) from an open pit mine about 56 miles (90 km) northwest of the mouth of Amakdedori Creek. The project is currently under federal environmental review by the U.S. Army Corps of Engineers. As part of this task, the location for a port facility will be selected to move materials to and from the mine. One option is to build the port at the mouth of Amakdedori Creek, a dynamic stretch of coast known for its volatile weather and ocean conditions.

A permanent year-round port facility constructed at Amakdedori on the west side of Cook Inlet will facilitate the direct loading of mineral concentrate onto bulk carrier vessels, as well as the delivery via barge of mining equipment and supplies. The port will include shore-based facilities to receive and store containers and fuel, as well as two 2-megawatt natural gas power generators, associated infrastructure, and facilities. The port’s marine component will include a causeway extending out to a marine jetty in 15 feet (4.6 m) of water depth. A dredged channel will be required to access the berth for ships. Port operations will facilitate up to 25 concentrate shipments via bulk carrier vessels each year, and up to 30 marine barge loads of mining equipment and supplies. Read more here and here.

About the background graphic

This ‘warming stripe’ graphic is a visual representation of the change in global temperature from 1850 (top) to 2021 (bottom). Each stripe represents the average global temperature for one year. The average temperature from 1971-2000 is set as the boundary between blue and red. The color scale goes from -0.7°C to +0.7°C. The data are from the UK Met Office HadCRUT4.6 dataset.
