The Nestucca River is 53 miles long and drains an area of 258 square miles. The headwaters of the Nestucca are located west of McMinnville, and the river flows in a west-southwest direction to the Nestucca Bay, which empties into the Pacific Ocean. The highest point on the river is at 2,200 feet above sea level, and tidal effects reach seven miles upstream to Cloverdale. The only impoundment, McGuire Reservoir, was constructed in 1969 near the headwaters and provides domestic and municipal water to McMinnville.

Forestry is the major land use in the watershed, and approximately 82% of the watershed are forest lands. Douglas fir is the predominant tree species in the watershed. Red alder and bigleaf maple dominate most rivers and streams, and oceanfront forests are dominated by lodgepole pine (shorepine).

The Nestucca watershed is a productive fishery resource, with many anadromous fish species (chum salmon, chinook salmon, coho salmon, searun cutthroat trout, and steelhead trout). Other species include lamprey, dace, sculpins, and pacific giant salamanders.
