<br />and application of the sediment rating curve to the historic record. Elliott et al.
<br />(1984) and Butler (1988a and b) computed annual loads at Deerlodge Park which
<br />included the Yampa River sediment load; a separate analysis involving the Little
<br />Snake River was not conducted.

<br />Channel Equilibrium Concepts
<br />The concepts of channel stability and equilibrium are important to the
<br />alluvial reaches of the Little Snake, Yampa and Green rivers. When the river
<br />channel morphology as governed by a variable sediment load is relatively constant
