Comments

Slope 4.2% by GIS, with much of that accounted at grade controls; conceivable that reference conditions may be a disorganized coarse plane-bed, but likely long-standing channel manipulations including localized dredging and snagging leave a mix of step-pool and riffle-pool features at this point in time. Surprising lack of refugia. Believe reference substrate should be cobble, significant sedimentation appears related to recent flood impacts
