Agriculture Irrigation Pause 9/23/25 - 10/2/25

Please read and share:

U.S. Fish and Wildlife Service personnel will apply lampricides to the Paw Paw River (Berrien and Van Buren Counties) to kill sea lamprey larvae burrowed in the stream bottom. Applications will be conducted between September 23 – October 2, 2025, in accordance with State of Michigan permits.

Application dates are tentative and may be changed based upon local weather or stream conditions near the time of treatment.*

Lampricides are selectively toxic to sea lampreys, but a few fish, insect, and broadleaf plants are sensitive. Persons confining bait fish or other organisms in stream water are advised to use an alternate water source because lampricides may cause mortality among aquatic organisms stressed by crowding and handling.

Agricultural irrigation must be suspended for 24 hours, during and following treatment.

*Berrien County Conservation District will post updates to the timeline if any changes are announced.
