Mill Canyon Culvert Replacement

2020-10-22 Mill Canyon_confluence with B

The project will provide start-up funds to replace the metal culvert on the Blackfoot River
Road at Mill Creek in the Blackfoot Narrows. The current culvert is a barrier to migrating
Yellowstone cutthroat that use this small stream for spawning and rearing. The project
will replace the culvert with a larger concrete box bridge with a natural bed that will
improve fish passage. A resting pool or weir will be designed at the downstream end of
the box bridge. The project is a cooperative effort of the U.S. Forest Service and Caribou
County.
