Trask River

The Trask River is in northwestern Oregon in the United States. It drains a mountainous timber-producing area of the Northern Oregon Coast Range west of Portland into Tillamook Bay and the Pacific Ocean. It is one of five rivers—the Tillamook, the Trask, the Wilson, the Kilchis, and the Miami—that flow into the bay.

The main stem of the river is 18 miles (29 km) long from where its two forks join at 45°26′23″N 123°36′41″W / 45.4398304°N 123.6115058°W / 45.4398304; -123.6115058 (Trask River (source)). The North Fork, 30 miles (48 km) long, rises in several forks itself in the Tillamook State Forest in western Washington County, west of Forest Grove, Oregon. It flows generally west into eastern Tillamook County. The South Fork, 10 miles (16 km) long, rises in southern Tillamook County at 45°20′56″N 123°39′12″W / 45.3489972°N 123.6534486°W / 45.3489972; -123.6534486 (South Fork Trask River (source)) and flows generally northward.

The river is known for its runs of Steelhead and Chinook salmon.

The river is named for Elbridge Trask who settled on the shores of Tillamook Bay in 1848. Trask's overland journey was described in the 1960 historical novel Trask by Don Berry, as well as two sequels. The novels are collectively known as the "Trask novels."
