South Bog Stream Brook Trout Habitat Restoration

FISHERY INTERIM SUMMARY REPORT SERIES NO. 07-05
JOB NO. F-027
INTERIM SUMMARY REPORT NO. 3 (2003-2007)
SUMMARY

South Bog Stream, a tributary to Rangeley Lake in Western Maine, provides habitat for wild brook trout and, to a lesser extent, landlocked salmon.  The lower portion of the stream historically served as spawning and nursery habitat for Rangeley Lake’s salmonid population.

A survey of South Bog Stream conducted in 2001 indicated a lack of deep pools, which provide critical adult brook trout habitat.  Consequently, a program was undertaken in 2004 to restore pools to that portion of the stream proximate to South Shore Drive with the goal of increasing the contribution of stream-reared brook trout to the lake.  Three stream restoration projects were implemented from 2004-2007 along a 1,900 foot-long reach two miles upstream of Rangeley Lake.  The entire study reach is being monitored annually to determine the efficacy of the projects in providing improved brook trout habitat as well as to determine whether restoration efforts, including reconstructed pools, retain their form and function in the face of high flows.  This report explains the parameters chosen to evaluate the project and summarizes the results of the first four years of measurements.  It will be necessary to collect several years’ more data before it will be known whether these projects are successful biologically and are resilient to stream flows.
