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 78.1 miles (125.7 km) (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 scenery, the Westfield River provides over 50 miles (80 km) 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, being only 2.1 miles (3.4 km) shorter.

The Chicopee River is an 18.0-mile-long (29.0 km) tributary of the Connecticut River in the Pioneer Valley, Massachusetts, known for fast-moving water and its extraordinarily large basin: the Connecticut River's largest tributary basin. The Chicopee River originates in a Palmer, Massachusetts village called Three Rivers as a confluence of the Ware, Quaboag and Swift rivers. It passes through Wilbraham, Ludlow, and the Indian Orchard neighborhood of Springfield.

After forming the border between Springfield and Chicopee, Massachusetts for a short distance, the river then flows in a sharply curving path through the city of Chicopee and into the Connecticut River. (Chicopee was part of Springfield until 1848.)

Smith College is a private liberal arts women's college in Northampton, Massachusetts, United States. It was chartered in 1871 by Sophia Smith and opened in 1875. It is a member of the historic Seven Sisters colleges, a group of women's colleges in the Northeastern United States. Smith is also a member of the Five College Consortium with four other institutions in the Pioneer Valley: Mount Holyoke College, Amherst College, Hampshire College, and the University of Massachusetts Amherst; students of each college are allowed to attend classes at any other member institution. On campus are Smith's Museum of Art and Botanic Garden, the latter designed by Frederick Law Olmsted.

Smith has 50 academic departments and programs and is structured around an open curriculum. Examinations vary from self-scheduled exams, scheduled exams, and take-home exams. Undergraduate admissions are exclusively restricted to women, including transgender women since 2015. Smith offers several graduate degrees, all of which accept applicants regardless of gender, and co-administers programs alongside other Five College Consortium members. The college was the first historically women's college to offer an undergraduate engineering degree. Admissions are considered selective. It was the first women's college to join the NCAA, and its sports teams are known as the Smith Bears.

The Five College Consortium (often referred to as simply the Five Colleges) comprises four liberal arts colleges and one university in the Connecticut River Pioneer Valley of Western Massachusetts: Amherst College, Hampshire College, Mount Holyoke College, Smith College, and the University of Massachusetts Amherst, totaling approximately 38,000 students. They are geographically close to one another and are linked by frequent bus service that operates between the campuses during the school year. The service is free for the students of the colleges.

The consortium was formally established in 1965, but its roots lay in cooperative efforts between the oldest four members of the consortium dating back to 1914.
