Instream Flow Program

The Instream Flow Program (ISF) is part of the Rivers Management and Protection Program. The program develops river-specific numerical criteria for stream flow protection and implements these criteria through water management plans. Because implementation can utilize water stored in lakes to enhance stream flow, the Rivers and Lakes Programs are working together to develop and implement protected flows for each of New Hampshire’s Designated Rivers.
