Most of these bars are in straight stretches of the river and there is every reason to believe that ( undor under ) the same flow conditions ( they theyr ) ( maintain nutintain ) about their same relative position . How - ever , long periods of uniform flow are unusual ( antl and ) ( with --with with ) variable flow the unstable condition of crossing ( bars 'bars bars ) previously discussed ( mil Niill ) prevail . Without exception the channel depths across these bars are shallow . The most common ( channel cliaanel ) depths at the bends and between the bars ranged from 3 to 5 feet . The drainage area tributary to the Colorado River below Moab is approximately twice as large as the area contributing to the Green below the mouth of the San Rafael . Courthouse Wash and Mill Creek , ( discharging discbarging ) into the Colorado River in the vicinity of ( Moab Aloab ) , and Kane Spring Wash , Lockhart Creek , Indian Creek , Salt Creek , and Red Lake Canyon coming in below Moab , all drain extensive areas subject to erosion . The load ( carried mrried ) by these ( tribu tribu- tribu ) ¬ taries during floods may have produced a ( consider consider- consider ) able amount of the canyon fill , because there is indication that during such periods they may fill channels 100 feet wide and 10 feet or more deep with a velocity sufficient to roll and otherwise move large boulders .
