Turnagain is subject to climate extremes and large tide ranges. - Bristol Bay ("Iilgayaq" in Central Yup'ik) is the eastern-most arm of the Bering Sea, at 57 to 59 North 157 to 162 West in Southwest Alaska. Bristol Bay is 400km (250mi) long and 290km, (180mi) wide at its mouth.

The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it a mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be seen as the northernmost part of the all-encompassing World Ocean. - The Gulf of Alaska is an arm of the Pacific Ocean defined by the curve of the southern coast of Alaska, stretching from the Alaska Peninsula and Kodiak Island in the west to the Alexander Archipelago in the east, where Glacier Bay and the Inside Passage are found. - The Bering Sea is a marginal sea of the Pacific Ocean. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelves. - Alaska is a U.S. state located in the northwest extremity of North America. The Canadian administrative divisions of British Columbia and Yukon border the state to the east; its most extreme western part is Attu Island; it has a maritime border with Russia to the west across the Bering Strait. To the north are the Chukchi and Beaufort seasthe southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. Alaska is the largest state in the United States by area, the 3rd least populous and the least densely populated of the 50 United States. Approximately half of Alaska's residents (the total estimated at 738,432 by the U.S. Census Bureau in 2015) live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy. - Knik Arm is a waterway into the northwestern part of the Gulf of Alaska. It is one of two narrow branches of Cook Inlet, the other being Turnagain Arm. Knik Glacier empties into the Knik Arm. The Port of Anchorage is located on the Arm. - The Alaska Peninsula is a peninsula extending about to the southwest from the mainland of Alaska and ending in the Aleutian Islands. The peninsula separates the Pacific Ocean from Bristol Bay, an arm of the Bering Sea. - Cook Inlet stretches from the Gulf of Alaska to Anchorage in south-central Alaska. Cook Inlet branches into the Knik Arm and Turnagain Arm at its northern end, almost surrounding Anchorage. On its south end merges with Shelikof Strait, Stevenson Entrance, Kennedy Entrance and Chugach Passage. - British Columbia (BC) is the westernmost province of Canada, with a population of more than four million people located between the Pacific Ocean and the Rocky Mountains. British Columbia is also a component of the Pacific Northwest and the Cascadia bioregion, along with the U.S. states of Idaho, Oregon, Washington and Alaska. - The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east. - Kvichak Bay is an arm on the northeast side of Bristol Bay in southern Alaska, at . It is long and wide.

It flows southwest from Lake Iliamna to Kvichak Bay , an arm of Bristol Bay , on the Alaska Peninsula . The communities of Igiugig and Levelock lie along the Kvichak River . The Kvichak is navigable along its entire length , and is used as a short cut by boats getting between Cook Inlet and Bristol Bay via the Lake Iliamna portage . The Kvichak River is home to the largest Red salmon run in the world . Commercial harvests are worth hundreds of millions annually . The Kvichak River is part of the watershed downstream of the proposed Pebble Mine . Historically , the river was navigated and subsistence fished by local Alaska Natives . The name of the river means from - or up to - great water , a reference to Iliamna Lake , Alaska 's largest freshwater lake . What is the relationship between 'kvichak river' and 'bering sea'?
