Description:
Palustrine floodplain of the Dirty Devil River is dominated by dead Sandbar Willow Scrub-shrub. A few live Cottonwood trees are along the sides of the canyon wall. The Dirty Devil River is dry in summer.
|
Conditions: This location is less than half a mile above the position of the current lake level of Glen Canyon Reservoir. The lake is currently 40 feet lower than full pool in 1998, but is 8 feet higher than low 2004 lake levels. The willow and cottonwoods in the Dirty Devil River were established when the lake level was higher and flooded the canyon.

Disturbances: The dropping lake level and low flow in the Dirty Devil River have stressed the scrub-shrub willow and caused them to die. |
