DNR presses second Brule lamprey barrier project
The Wisconsin DNR renews plans to build a new concrete lamprey barrier on the Bois Brule River to block sea lamprey while allowing trout passage. The overhaul uses a 150 foot run and removable plate to lift trout over a 6 foot barrier, with lamprey destroyed and land-buried during spawning. Funding totals about 240000 with 100000 from the US Fish and Wildlife Service and 140000 from state trout stamps.

New Brule Lamprey Barrier Aims To Boost Trout Run
Biologist Frank Pratt explains a redesigned 12 by 150 foot lamprey barrier at Bois Brule that blocks sea lamprey while letting trout pass. The barrier, funded by anglers, will enclose a counting station to gauge spawning runs and collect data for yearly harvest plans.
