From The Pueblo Chieftain (James Amos):
The site of the proposed Red Creek Reservoir is a mile from the Arkansas River near the borderline of Pueblo and Fremont counties. District Manager Larry Howe-Kerr said this part of the reservoir study will include drilling to study the rock under the reservoir site. That and other studies will determine if the reservoir could hold water and if it would be strong enough. The drilling could begin as soon as next week.
