The good news is that the Crystal River is healthy. She winds like a lazy snake through wetlands protected by the Sleeping Bear Dunes National Lakeshore, so when excessive rain or snowmelt inundate her environment—as happened during record flooding in early April—the extra water has a place to go. The other good news is that the removal of culverts in three locations under County Road 675 during the past five years has helped the river flow more freely and relieves pressure during high water events. The bad news is that two more culverts remain downstream of The Mill. Those culverts restrict water flow beneath Overbrook Drive. The other bad news is that scientists who study climate change in the Great Lakes region predict more frequent and more intense extreme weather events, including rainstorms.

Just outside of Glen Arbor, a well-traveled section of County Road 675 is imperiled as it crosses three sets of undersized culverts slowly crumbling into the Crystal River. That’s a multi-million-dollar problem for the Leelanau County Road Commission. The engineering plans call for the construction of a concrete and steel structure to replace the culverts under CR 675 closest to M-22. That will keep the two road surfaces closely matched in elevation. The two sets of culverts further east, including the “shoot-the-tube” culverts, are to be replaced with classic wood bridges providing a lot of headroom for paddlers, ending the need for portages across the road. Plans call for the replacement of the Tucker Lake overflow culvert with a wide and substantial concrete box culvert.
