What is the gradient (change in elevation/length of river) of the Naugatuck River?

As the river flows south from Torrington to Derby it drops approximately 540 feet in elevation, resulting in a relatively steep gradient of approximately 13 feet per mile. Consequently, the river is a predominantly rapidly flowing river for most of its length, characterized occasionally by rapids.

explanation:

on disadvantage of hydroelectric power is the cost. another disadvantage of using hydroelectric power is finding a water source powerful enough to harvest hydroelectric power.
