Deerfield by the numbers: Watershed Facts and Figures
		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 hydrolelectric 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.

• List of tributaries in MA
• More information at the USGS site: The basin in MA contains relatively few lakes and ponds, and most of these were created or enlarged by earthen dams. There are a total of 23 lakes and ponds, 16 of which cover at least 10 acres. The largest lake is Sherman Reservoir in Rowe, which has an area of 162 acres. The natural flow of the Deerfield River has been modified by the reservoirs in Vermont. Sherman Reservoir provides water for generation and for some once-through cooling water at Sherman Hydro Station, also for whitewater releases at No. 5 dam. Water released from the reservoirs during periods of power generation causes diurnal fluctuations in streamflow. The reservoirs help control floods in the basin and augment flow in the Deerfield River during low-flow periods.

• River elevation: drops approximately 2000 feet from the headwaters in southern Vermont to the confluence with the Connecticut River in Greenfield, Massachusetts.
• Altitudes: range from 2,841 to 120 ft above sea level
• The river flows southeastward through the Berkshire Hills of Massachusetts in a narrow valley bordered by steep slopes that rise, in places, more than 1,000 ft above the river. Near the Connecticut River, the terrain is much flatter. Overall, the gradient of the Deerfield River is quite steep, averaging 46.8 ft/mi from its headwaters to the USGS streamflow gage near West Deerfield, a distance of about 69.5 river MI

• 20 town in 3 Massachusetts counties (Berkshire, Franklin, Hampshire)
  Adams, Ashfield, Bernardston, Buckland, Charlemont,Colrain, Conway, Deerfield, Florida, Goshen, Greenfield, Hawley, Heath, Leyden, Monroe, North Adams, Plainfield, Rowe, Savoy, Shelburne
• 35,300 people in the Massachusetts section (1990 Census data)

• About 78 percent of the basin is forested and only about 3 percent is urbanized.
• There are 9 dams and 10 hydroelectric developments on the mainstem
