DISCOVERYThe Discovery Channel debuts a new four part documentary focused on dwindling supply of Colorado River water. Trailers for the program called “Killing the Colorado” reveal it will focus on how increased use and the ongoing drought are sucking the river dry.

The documentary is scheduled to air at 9:00 p.m. Thursday. Anyone interested in tuning in should consult their local listings as airtimes can vary from community to community.
