Gross Reservoir could double in size under plan

Environmentalists say project might deplete West Slope waterways

Drew Peternell, director of the Boulder-based Colorado Water Project, is worried less about picnic tables and more about Western Slope streams that are already heavily taxed getting damaged by projects like this one.

He said his group hasn't taken a formal position on whether to oppose the project.

"Our biggest concern with this whole project is the additional depletions in streamflows that it will cause on the Western Slope," he said. "The rivers and streams in Grand County have really been hit hard by diversions to the Front Range."
