  • Subject: Upper Colorado and San Juan Recovery Program social media implementation
  • Details: We're launching joint social media sites (facebook, Twitter, Flickr) for the Upper Colorado River Endangered Fish Recovery Program and the San Juan River Basin Recovery Implementation Program to help us communicate our messages about the recovery programs to new and broader audiences and to allow us to get more photos, videos, and clickable URLs in front of those audiences. We envision our social media sites primarily as places to educate the general public about the endangered fish and the recovery programs.
