The Central Ridges and Valleys Region encompasses the Potomac River tributary watersheds of Pennsylvania, the Juniata River basin and the State College region. It covers a large portion of Pennsylvania’s section of the Chesapeake Bay Watershed.

The region is characterized by long, forested mountain ridges interspersed with picturesque rural valleys dominated by farmland. This region also hosts thousands of acres of public land, protecting large areas of forestland that are available to the public for outdoor recreation. Many of the valleys are drained by high quality coldwater streams that support healthy populations of trout and attract anglers from around the world.
