Sandy River Brook Trout Habitat Restoration

FISHERY INTERIM SUMMARY REPORT SERIES NO. 07-05
JOB NO. F-027
INTERIM SUMMARY REPORT NO. 1 (2006-2007)
SUMMARY

An 800-foot long reach of the upper Sandy River was restored in August 2006 to improve wild brook trout habitat.  A variety of techniques were used, including cabled logs to divert and concentrate flow; rock weirs to create and maintain large pools and provide cover, and paired boulders to scour shallow pools and provide cover.  Ten semi-permanent transects were established and measured prior to and after the construction phase.  Two additional transects were established post-construction to monitor pool depths immediately downstream of the rock weirs.  Additional evaluation methods included pebble counts to monitor changes in substrate size and electrofishing to determine changes in fish species diversity and abundance.  As a result of high flows in October 2006, there was considerable displacement of logs and paired boulders, and two of the rock weirs were damaged.  The two compromised weirs were repaired in October of 2007.  Annual monitoring results are presented, and sampling will be repeated on an annual basis to determine the durability and effectiveness of the structures.
