Stream Obstruction Vermont law (10 V.S.A. § 4607) prohibits the installation of a structure that prevents fish movement, such as a rack, weir or other obstruction, unless an approval has been granted by the Commissioner of Fish and Wildlife. Projects where this is commonly an issue include culvert installation and dam construction or reconstruction. In cases where other Agency permits, such as a Dam Order or Stream Alteration Permit, are required, this issue is addressed as part of that permit process. In cases where other permits are not involved, a request may be sent to the Department of Fish and Wildlife. This is usually the case only if the stream involved is in a small watershed with a drainage area less than 10 square miles.
