Conservation Planning for the Colorado River in Utah - Presence of Still Water Plus 20 m for Riparian Understory Model

This map shows stillness of water near bank vegetation within 15 m of the channel boundary (2011) of the Colorado River mainstem between the Utah Colorado border and the upper pool of Lake Powell, Utah (146 miles). The channel boundary was mapped from public available NAIP imagery flown on June 28, 2011, when the river flow was 886 m3/s at the Cisco gage. The channel is subdivided into channel types: main channel, secondary channel, backwater, isolated pool and tributary channel.
