The restoration treatment will included log and boulder placements, invasive vegetation removal, and native vegetation plantings. This is a low gradient site primarily comprised of riffles and a few pools. Some side-channel habitat is also present. Gravel and cobble are the primary substrate types. A few old, artificially placed habitat logs were noted. 2014 REACH: 1 __________ LOCATION: T02S-R02E-S12SW
