Service Description: New Hampshire's rivers and streams comprise one of its most important natural resources, historically vital to New Hampshire's commerce, industry, tourism, and the quality of life of New Hampshire people. It is the policy of the state to ensure the continued viability of New Hampshire rivers as valued economic and social assets for the benefit of present and future generations. The state shall encourage and assist in the development of river corridor management plans and regulate the quantity and quality of instream flow along certain protected rivers or segments of rivers to conserve and protect outstanding characteristics including recreational, fisheries, wildlife, environmental, cultural, historical, archaeological, scientific, ecological, aesthetic, community significance, agricultural, and public water supply so that these valued characteristics shall endure as part of the river uses to be enjoyed by New Hampshire people (RSA 483:1).
To complement and reinforce existing state and federal water quality laws, and maintain instream flows along protected rivers, or segments thereof, in a manner that will enhance or not diminish the enjoyment of outstanding river characteristics pursuant to RSA 483:1. It is also the intent that the scenic beauty and recreational potential of such rivers shall be restored and maintained, that riparian interests shall be respected. Coverage update on 7/31/2018.

Description: Designated River Corridor means the river and the land area located within a distance of 1,320 feet of the normal high water mark or to the landward extent of the 100-year floodplain as designated by the Federal Emergency Management Agency, whichever distance is larger, per RSA 483:4, XVIII. The layer was constructed by creating a 1,320-foot buffer from a composite of NH Designated Rivers from the following NHGS 2022 shapefiles: NHDFlowline, NHDArea, and NHDWaterbody. Portions of NHDES' Floodplain100Yr_Dissolve shapefile that were determined to be associated with the mainstem of the designated river and extend beyond the 1.320-foot buffer were added to the shapefile. Created specifically to support the Rivers & Lakes Program's NH Designated River Corridors Web Map.
