A Federal Consistency Certification has been submitted to the Delaware Coastal Management Program for the following: DNREC Open Marsh Water Management (2023.0025)

The DNREC Division of Fish and Wildlife, Mosquito Control Section is applying to continue to use the technique of Open Marsh Water Management (OMWM) as the primary form of larval mosquito control within tidal wetlands throughout Delaware. OMWM provides mosquito control by altering the topography and hydrology of salt marshes by creating permanent waterbodies that provide fish habitat and access to mosquito breeding areas. Material excavated from the salt marsh surface would be spread in a thin layer across the marsh to fill mosquito larval “pothole” habitat adjacent to areas not directly addressed by the excavated features.
