For centuries the Susquehanna was used as a source of nourishment, protection, travel, trade, and reverence by Native Americans who inhabited its coastlines. For approximitely 11,000 years before white encroachment the Susquehannocks, an Iroquois-speaking tribe of the Northeast, arrived in the area, birthed a civilization, and came to control the land around the Susquehanna. The area has become much of what it is today due to those first inhabitants, and furthermore, the Susquehanna still holds major iinfluence over the lives of those within the watershed.
