ABSTRACT:
	The dataset provides surveyed longitudinal elevation profiles of the water surface along the center-line of twelve randomly selected study reaches located in the Lookout Creek basin at the H.J. Andrews Experimental Forest in the western Cascades Mountains of Oregon. Streams were surveyed with an engineers level and stadia rod between Jan 2000 and August 2001; survey locations were regularly spaced along the length of the channel using a tape measure stretched between stakes along the center line of the channel. The slope of the water surface profile were categorized into three distinct types of units, called Slope Units, and were defined according to slope categories for flat water, steep water, and step units (FLATs, STEEPs and STEPs). The slope units were categorized into 12 different qualitatively descriptive classifications to further describe the morphology of the survey, and a perceived cause of the slope units. Additionally, channel widths were recorded to examine the effects of channel constraint on the geomorphic features of the study reaches.
