Bear Creek is a small,
and until recently, severely degraded tributary to the lower Blackfoot River. The
stream flows through commercial forest and small private inholdings before entering the
Blackfoot River at river mile 12.2 with a base flow of 3-5 cfs. The stream lacked
pools because of channelization, logging and improper grazing in the riparian
area. Limited fish passage at two culvert crossings and losses of fish to two
irrigation ditches were also identified problems. In order to prioritize restoration
resources, we developed a fisheries-based restoration priority scorecard, based on
biological, social and financial considerations, for 83 impaired tributaries of the
Blackfoot River. Bear Creek ranked 49 of 83 streams surveyed.

After construction.
From 1995 to 1998, several steps were
taken to improve fish passage, reduce irrigation impacts and improve riparian land
management. In 1998, a project was implemented that included the reconstruction of
1,870 feet of B4 channel and included an additional 2,000 feet of habitat
restoration. This project included riparian livestock management improvements
(fencing and off-stream water) and shrub plantings along the length of the project.
| In 1998,
post project habitat evaluations and pre-project fish populations monitoring were
completed in addition to temperature monitoring for the Bear Creek Channel Reconstruction
Project. The habitat survey was undertaken in the newly constructed channel. An
overview of general habitat parameters is outlined below. |
