North Branch Westfield River
The North Branch of the Westfield River starts at the town of Savoy, Massachusetts in the Berkshires. It flows southeasterly to the town of Cummington where it follows Route 9 to the junction with the Swift River. Here it turns sharply south and flows through the picturesque Pork Barrel region to West Chesterfield. It continues through a wilderness region to the Knightville Reservoir. From here it continues south for about 5 miles to Huntington, Massachusetts where it becomes the main branch of the Westfield River. The Middle Branch and the West Branch join it in this section.
