The Westfield River is a major tributary of the Connecticut River located in the Berkshires and Pioneer Valley regions of western Massachusetts. With four major tributary branches that converge west of the city of Westfield, it flows (measured from the source of its North Branch) before its confluence with the Connecticut River at Agawam, across from the city of Springfield's Metro Center district. Known for its whitewater rapids and scenic beauty, the Westfield River provides over of whitewater canoeing and kayaking, in addition to one of the largest roadless wilderness areas remaining in the Commonwealth.The Westfield River is the Connecticut River's longest tributary in Massachusetts, although the Chicopee River's basin is much larger, and contributes more water to the Connecticut. The Connecticut's northern tributary, the Deerfield River, is nearly as long as the Westfield—only shorter than the Westfield.During the mid-20th century, the Westfield River was so polluted that it would change color based on the nature of the contaminant. Today, the river is clean enough for swimming. It is a state and locally managed river featuring native trout fishing and rugged mountain scenery in the context of a historical mill town settlement (at Westfield).HistoryOn its initial discovery by Massachusetts Bay Colony explorers John Cable and John Woodcock in 1635, the area stretching from the Westfield River's confluence with the Connecticut River to Westfield itself—which, the next year, would all be encompassed in the settlement that came to be known as Springfield—was named the "Agawam River", after the name of the Native American people then occupying the area. Historical literature often refers to Springfield as sitting at the confluence of the Connecticut River with the western Agawam River and eastern Chicopee River. This "Agawam River" is now known as the Westfield River, and should not be confused with the Agawam River in southeastern Massachusetts, which was named in tribute to Springfield's peaceful Natives.
