Mount Haggin Culvert Removal and Replacement

Project Description

This project proposes to address multiple fish passage barriers to native fish in the Mount Haggin Wildlife Management Area (WMA). Currently, there are 4 undersized and perched culverts that restrict upstream movement to the native Arctic graying and Westlople cuttthrout trout. The project proposes to completely remove 2 of the 4 culverts that are unnecessary and out of commission and replace the other 2 culverts to facilitate fish passage and stream connectivity.

This project comes off the heels of BHWC’s many years of involvement in remedy and restoration on the Mount Haggin WMA and Montana Fish, Wildlife, and Parks efforts to restore the French Creek drainage to a completely native fishery.  The project will open 7.5 miles of stream habitat to the restored French Creek population and will represent one of the largest interconnected populations of Westslope Cutthroat trout in the upper Missouri River drainage and the only population of fluvial Arctic grayling in the absence of non-native species.  The addition of 7.5 additional miles due to this project will bring the total mileage of the occupied stream to nearly 47.5 miles!

Project Status

BHWC is currently working with project partners the USFWS and MFWP to secure funding and finalize designs.


Results

Project results will be shared after implementation.  Construction is tentatively planned for the fall of 2023.
