From Stratton Mountain in Southern Vermont to Greenfield in Massachusetts, the Deerfield River watershed typifies rural New England at its best. Our rugged topography boasts spectacular scenic settings and exciting recreational opportunities.
This topography has also attracted large electric utilities and their accompanying dams: we have ten hydroelectric developments on the mainstem, some built as far back as 1911.
One of the coldest and cleanest rivers in the region, the Deerfield River is home to native and stocked trout and is the site for Atlantic salmon restoration.
