The state of Illinois now has one known alert:

Hennepin Canal east of Colona
There is a huge hole, approximately 15 feet by 75 feet, that cuts through the Hennepin Canal path east of Colona, and there's really no good way around it. The hole appeared In late December after a levee broke on the north side of the Green River east of the aqueduct that carries the Green River over the Hennepin Canal. Seeking the river basin, the floodwaters eventually pushed through the canal levee, compromising the trail and creating the big gap, which is about a quarter mile west of the aqueduct.
ADT is requesting authorities to clearly mark a detour around the break to assist long distance hikers and bikers using the trail. Once that information is available, it will be posted here.

Please contact your state coordinator if you have a trail alert that should be added to this page.
