There are approximately 85 hydroelectric generation facilities operating in Vermont and on waters bordering other states. Under state law, the Agency of Natural Resources is charged with ensuring that these projects are operated so that the state's rivers and lakes - which are public trust resources - continue to meet Vermont's water quality standards.
Protection of instream flow is a critical aspect of managing our waters in a sustainable manner. While the benefits of flow regulation – hydroelectric power, flood control, water for numerous purposes – are obvious, the impacts often are not. In Vermont, we have focused much attention on maintaining adequate minimum flows to protect aquatic habitat and stream ecology, but other aspects of flow protection are equally important.
