Energy policy — hydroelectric: Accuracy of Pitkin County’s streamflow data in question

From The Aspen Daily News (Curtis Wackerle):

Boulder firm AMEC Earth and Environmental, hired by Pitkin County, found that the city may have overestimated stream-flows by as much as 30 percent at the diversion points where water would be taken out of Castle and Maroon creeks to feed the hydroplant. “If such an error exists and is ignored,” wrote Tim McFlynn, who has been organizing the mediation effort, “hydropower and revenue generation would be overestimated and healthy bypass flows in streams would be similarly impacted.”

The closed-door mediation session was scheduled for Feb. 8 in an attempt to bridge the gap between supporters and opponents of the project. But comments from the panel of experts hired by the county’s Healthy Rivers and Streams board for $50,000, which were submitted to the city two weeks ago, have prompted facilitators to take a time-out.
