Conservation Permits: Wetlands Protection

November 14, 2022 Update:

Lexington, a Department of Environmental Protection Northeast Regional Office (DEP NERO) Community, remains in a mild drought. As such, any observations of dry perennial streams in this region still may not be submitted as proof that a stream is intermittent in the northeast drought region. Commissions may not accept observations of dry stream made between May 1, 2022, and the declared end of the drought.

Further, photos of dry stream taken before May 1, 2022 for this purpose, must also not be taken during drought conditions and always check the Past Drought Status Page to see if older photos were taken during a declared drought before submitting as evidence.
