Location of the mouth of the West Twin River in Washington

The West Twin River is a stream on the Olympic Peninsula in the U.S. state of Washington. It originates in the northern Olympic Mountains and flows north, emptying into the Strait of Juan de Fuca just east of East Twin River. [2]

Olympic Peninsula peninsula

The Olympic Peninsula is the large arm of land in western Washington that lies across Puget Sound from Seattle, and contains Olympic National Park. It is bounded on the west by the Pacific Ocean, the north by the Strait of Juan de Fuca, and the east by Hood Canal. Cape Alava, the westernmost point in the contiguous United States, and Cape Flattery, the northwesternmost point, are on the peninsula. Comprising about 3600 square miles, the Olympic Peninsula contained many of the last unexplored places in the Contiguous United States. It remained largely unmapped until Arthur Dodwell and Theodore Rixon mapped most of its topography and timber resources between 1898 and 1900.

U.S. state constituent political entity of the United States

In the United States, a state is a constituent political entity, of which there are currently 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory and shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders. Four states use the term commonwealth rather than state in their full official names.

Olympic Mountains mountain range

The Olympic Mountains are a mountain range on the Olympic Peninsula of western Washington in the United States. The mountains, part of the Pacific Coast Ranges, are not especially high – Mount Olympus is the highest at 7,965 ft (2,428 m); however, the eastern slopes rise out of Puget Sound from sea level and the western slopes are separated from the Pacific Ocean by the low-lying 20 to 35 km wide Pacific Ocean coastal plain. The western slopes are the wettest place in the 48 contiguous states. Most of the mountains are protected within the bounds of Olympic National Park and adjoining segments of the Olympic National Forest.

Course

The West Twin River originates in the Olympic National Forest in the northern portion of Olympic Peninsula. It flows north and east, entering the Strait of Juan de Fuca near the town of Twin, less than 0.5 miles (0.80 km) east of the mouth of the East Twin River. [2]

Olympic National Forest

Olympic National Forest is a U.S. National Forest located in Washington, USA. With an area of 628,115 acres (2,541.89 km2), it nearly surrounds Olympic National Park and the Olympic Mountain range. Olympic National Forest contains parts of Clallam, Grays Harbor, Jefferson, and Mason counties. The landscape of the national forest varies, from the temperate Olympic rain forest to the salt water fjord of Hood Canal to the peaks of Mt. Washington.

Puget Sound sound along the northwestern coast of the U.S. state of Washington

Puget Sound is a sound along the northwestern coast of the U.S. state of Washington, an inlet of the Pacific Ocean, and part of the Salish Sea. It is a complex estuarine system of interconnected marine waterways and basins, with one major and two minor connections to the open Pacific Ocean via the Strait of Juan de Fuca—Admiralty Inlet being the major connection and Deception Pass and Swinomish Channel being the minor.

Strait of Juan de Fuca strait

The Strait of Juan de Fuca is a large body of water about 154 kilometres (96 mi) long that is the Salish Sea's outlet to the Pacific Ocean. The international boundary between Canada and the United States runs down the center of the Strait.

Strait of Georgia strait between Vancouver Island and the mainland coast of British Columbia, Canada and Washington, United States

The Strait of Georgia or the Georgia Strait is an arm of the Pacific Ocean between Vancouver Island and the extreme southwestern mainland coast of British Columbia, Canada and the extreme northwestern mainland coast of Washington, United States. It is approximately 240 kilometres (150 mi) long and varies in width from 20 to 58 kilometres. Along with the Strait of Juan de Fuca and Puget Sound, it is a constituent part of the Salish Sea. Archipelagos and narrow channels mark each end of the Strait of Georgia, the Gulf Islands and San Juan Islands in the south, and the Discovery Islands in the north. The main channels to the south are Boundary Pass, Haro Strait and Rosario Strait, which connect the Strait of Georgia to the Strait of Juan de Fuca. In the north, Discovery Passage is the main channel connecting the Strait of Georgia to Johnstone Strait. The strait is a major navigation channel on the west coast of North America, owing to the presence of the port of Vancouver, and also due to its role as the southern entrance to the intracoastal route known as the Inside Passage.

Nooksack River river in the United States of America

The Nooksack River is a river in the northwest part of the U.S. state of Washington. It drains an area of the Cascade Range around Mount Baker, near the Canada–US border. The lower river flows through a fertile agricultural area before emptying into Bellingham Bay and, via the Strait of Juan de Fuca and the Strait of Georgia, the Pacific Ocean. The river begins in three main forks, the North Fork, Middle Fork, and South Fork. The North Fork is sometimes considered the main river. Including the North Fork, the Nooksack is approximately 75 miles (121 km) long. All three forks originate in the Mount Baker Wilderness.

The Sol Duc River is a river in the U.S. state of Washington. About 78 miles (126 km) long, it flows west through the northwest part of the Olympic Peninsula, from the Olympic Mountains of Olympic National Park and Olympic National Forest, then through the broad Sol Duc Valley. Near the Pacific Ocean the Sol Duc River joins the Bogachiel River, forming the Quillayute River, which flows about 4 miles (6.4 km) to the Pacific Ocean at La Push. Although the Quillayute River is short, its large tributary rivers—the Sol Duc, Bogachiel, Calawah, and Dickey Rivers—drain the largest watershed of the northern Olympic Peninsula, 629 square miles (1,630 km2). The Sol Duc's watershed is the largest of the Quillayute's tributaries, at 219 square miles (570 km2).

The boundary between Saratoga Passage and Skagit Bay is between Polnell Point on Whidbey Island and Rocky Point on Camano Island.

The Pysht and nearby Hoko River are the two largest streams flowing into the southwestern portion of the Strait of Juan de Fuca. The watershed of the Pysht River drains a region of industrial forest lands; 98% of the watershed is zoned commercial forestry and the remainder rural. Nearly all of the forests have been logged at least once and most trees are less than thirty years old. The upper portions of the watershed, which feature steep gradients, are owned by the United States Forest Service. The lower reaches, with low gradients, are largely owned by two industrial forest owners.
