In the summer of 2005, River Design Group, Inc. (RDG), Montana Fish, Wildlife & Parks and the Flathead National Forest implemented an in-channel large wood reintroduction project for Hallowat Creek, an important bull trout stream in the North Fork Flathead River drainage near Big Creek, Montana. The project was an effort to re-establish stable habitat-forming large wood structures that were compromised by fire suppression efforts associated with the Moose Fire on the western flank of Glacier National Park in 2001. Fire suppression activities included cutting large wood in the stream corridor with the intention of using Hallowat Creek as a fire break. Subsequent runoff events mobilized the cut large wood, leading to habitat simplification, localized channel scour, and spawning gravel loss.
