Abstract
Two studies were completed in the mid 90s to determine the limiting factors for salmon production in the San Juan watershed. Lack of over-wintering habitat was determined as a keylimiting factor. Several habitat restorationprojects were completed between 1996 and 2001 in the San Juan watershed. The Harris Creek side-channel location was reviewed by DFO in 1997. A stream originating from Lizard Lake was the original water source for this side-channel but the channel would dry up in the summer, trapping juvenile salmon in the pools or they would die in the dried up channels. DFO developed a plan to increase the channel to approx. 1.7kms by piping water from Harris Creek into the constructed side-channel. In 2004 surveys commenced for determining ground water depths, dissolved oxygen levels and water temperatures. These measurements (through a series of test pits) concluded the area to be suitable for side-channel habitat and construction. In 2006 a road was constructed to access the upper portion of the side channel and to act as a berm to protect the side channel from the floodwaters of Harris Creek. The road was also used to deliver material (LWD, Pipe, Intake structure and rip rap) to the side-channel construction site. Construction of a 750m long 6m wide channel began in the summer of 2006. This included the installation of the water intake (from Harris Creek), completion of the road construction ? including the crossing and channel construction.
