The Delaware Department of Natural Resources and Environmental Control (DNREC), Division of Fish and Wildlife, Mosquito Control Section is seeking a Department of the Army 10 year maintenance permit to continue performing Open Marsh Water Management (OMWM) within the tidal wetlands of Sussex, Kent and New Castle Counties as the primary and preferred mosquito control technique. OMWM provides effective and permanent biological control of larval mosquito populations while significantly reducing the need to apply mosquitocide chemicals. The Delaware Mosquito Control Section has been successfully using OMWM to control mosquitoes in Delaware's tidal marshes since 1979. More details are available in the "Public Notice" and "Open Marsh Water Management Guidelines" attachments. Public comments are requested by May 14, 2023.
