Watershed Assistance

Working with partners and stakeholders to protect and restore surface water in New Hampshire.

The NHDES Watershed Assistance Section works with local organizations, statewide nonprofits, municipalities, regional planning commissions, other programs within NHDES, EPA New England, and other state agencies to improve water quality in New Hampshire at the watershed level by implementing the New Hampshire Nonpoint Source Management Program Plan.

At the heart of this plan is the protection and/or restoration of surface waters in New Hampshire enabled by far-reaching collaboration with a diverse portfolio of watershed management stakeholders throughout the state.
