From the Aspen Daily News (Curtis Wackerle):
Water levels in Maroon Creek will be drawn down from the current flow of about 50 cubic feet per second to 14 cfs on Tuesday and Thursday this week as the city of Aspen demonstrates the “look and feel” of a stream running near the minimum rate associated with the proposed Castle Creek hydropower project. The demonstrations are technically site visits with Aspen City Council members, and thus are public meetings…
Maroon Creek has a state-mandated minimum instream flow of 14 cfs. The site visit is intended to allow council members to observe the “look and feel of a stream at those levels,” Hornbacher said.
