Rock Creek Restoration Objectives: restore migration corridors for native fish; restore natural stream morphology to improve spawning and rearing conditions for all fish using the system. Project Summary Rock Creek, the largest tributary to the lower North Fork of the Blackfoot River, has been the focus of restoration since 1990. Rock Creek, a basin-fed stream over most of its length, receives significant groundwater inflows between mile 1.2 and 1.6. Rock Creek was degraded over most of its 8.2-mile length due to a wide range of past channel alterations and riparian management activities (Pierce 1990; Pierce et al. 1997). In 2002. the Blackfoot cooperators reconstructed -3,000' of floodplain in an over-widened section of stream between mile 3.0 and 3.8. This project focused on importing sod-mats and included shrub plantings, along with fencing and off-stream water developments. To date, this brings the total amount of restored stream to -7.2 miles. Fish Populations Rock Creek supports spawning migrations of brown trout and rainbow trout in lower reaches, and brook trout throughout the length of the stream. Middle reaches provide bull trout rearing and fluvial migration corridors to small headwater populations, ki 2002, we continued to survey fish populations in a section (mile 1.6) of stream reconstructed in 1999. Our surveys show an increase in densities (Figure 34) and a shift from a brook trout to a more brown trout dominated community (Appendix A). Bull trout and rainbow trout also periodically utilize this portion of Rock Creek in lower abundance. Figure 34. Total trout densities (fish > 4.0") for Rock Creek at mile 1.6,2001-03.
