Little Rock Creek
Enhancement of habitat in this portion of Little Rock Creek may result in a higher local standing stock
of trout by improving conditions for adult trout, although over-arching problems with the trout population
may periodically negate any gains.
In straighter reaches with stream bank erosion, brush packing will be employed to protect banks
and encourage deposition of alluvial material. This will be done to prevent over-widening of the
stream, and perhaps even narrow the channel in places. Locally available alder or willow will be
cut in appropriate lengths for eroded areas. Stakes 3 feet in length will also be cut from the same
materials, and used to anchor brush in place. See below for specific locations.
Three outside bend locations are exhibiting more significant erosion, which may warrant more significant
measures. Additionally, these outside bends present opportunities to enhance adult trout habitat due to
the great water depths present in these locations. Two potential options are possible to achieve both
erosion control and habitat enhancement: Sky Hook structures and root wad revetments.
Sky Hook structures create undercut bank habitat that is idea for adult brown trout, and the rock
incorporated into the structures creates significant stability. Root wad revetments can provide
overhead cover for trout, in addition to deflecting current away from streams to reduce erosion.
Plantings of floodplain tree species should accompany work on poorly vegetated bends, in addition to
willow stake plantings. This should provide increased stability in the long term.
