Conservation Planning for the Colorado River in Utah - 2010 Low Flow

We mapped surface water from high resolution photography taken on September 16, 2010, at a stream flow of 96.5 m3/s (3,410 ft3/s, Cisco gage). We subdivided surface water into six categories: primary channel, secondary channel, split flow channel, backwater, isolated pool, and tributary channel, similar to that of fish habitat methods used extensively in Oregon. Channel types that are not primary channel are considered ‘off-channel’.
