Investigations of Sources of Contaminants of Concern in the San Juan River

Metals attached to suspended sediments or dissolved in river water pose a potential health risk to communities that depend on that water for agricultural and domestic uses. Exceedances of Navajo Nation surface water quality standards for metals (especially lead and arsenic) indicate that communities on the Navajo Nation along the San Juan River are exposed to this potential risk.

Is timing really everything? Evaluating Resource Response to Spring Disturbance Flows

Glen Canyon Dam has altered ecological processes of the Colorado River in Grand Canyon. Before the dam was built, the Colorado River experienced seasonable variable flow rates, including springtime flooding events. These spring floods scoured the river bottom and enhanced natural processes that sustained the Colorado River ecosystem. Since the dam’s construction in 1963, springtime floods have...
