The Merrimack River flows for 115 miles from its source at the confluence of the Pemmigewasset and Winnipesauke Rivers, through central New Hampshire and eastern Massachusetts and into the Atlantic at Newburyport. The Merrimack has a watershed of over 5,000 square miles. Twelve thousand years ago, the nomadic Paleo Indians fished the Merrimack, as it flowed through what is now Manchester, New Hampshire. Around 6,000 years later, the nomadic tribes began settling. These early natives used crude nets across the river to trap the fish. Later, permanent weirs of brush and branches, and eventually stone weirs, trapped the fish and made catching them easier.
