PORTAGE, Wis. – The Wisconsin Department of Natural Resources (DNR) today announced that the Wisconsin River is expected to rise to major flood levels in the Portage area on Wednesday, April. 15, 2026.
As a precaution, DNR staff members are monitoring the Caledonia and Lewiston levees twice daily. If river levels reach 19.4 feet, monitoring will expand to a round-the-clock surveillance schedule. Currently, river levels are projected to rise to 20.3 feet; flood stage is 17 feet and the river is now at 18.90 feet.
