Comments:
Channel has been straightened alongside correctional facility and bermed below culvert. Armoring appears to be holding much of bank stable w/in reach. Much scour noted at top of reach at culvert outfall. Bed features altered as a result of straightening and increased transport capacity. Difficult to assess what original sinuosity and floodplain connectivity was throughout this area because it has been altered for so many years. Stream type departure for bedform (from riffle-pool to plane bed) has been noted in the QA notes and overall summary table, but not checked in step 2 b/c it is not a sub-reach.
