Holly River

The Holly River is a tributary of the Elk River in central West Virginia in the United States. Via the Elk, Kanawha, and Ohio Rivers, it is part of the watershed of the Mississippi River, draining an area of in a rural region of the Allegheny Mountains. It is approximately long, or including its Left Fork. The river was named for the holly bushes along its course.
The Holly River is formed by the confluence of its Left Fork and its Right Fork:

The Left Fork Holly River, long, rises in northeastern Webster County, approximately southwest of Pickens, and flows generally westward through the southern part of Holly River State Park and the community of Hacker Valley into eastern Braxton County.
The Right Fork Holly River, long, rises in north-central Webster County, approximately northeast of Webster Springs, and flows generally northwestward through the communities of Diana and Big Run into eastern Braxton County.

From the confluence of its left and right forks, the Holly River flows westward as an arm of Sutton Lake, formed by a dam on the Elk River, to its mouth approximately east of Sutton. The Holly River’s course and the lower reaches of the left and right forks are part of the Elk River Wildlife Management Area.
According to the West Virginia Department of Environmental Protection, approximately 97% of the Holly River watershed is forested, mostly deciduous. Approximately 2% is used for pasture and agriculture.
