Great interface, missing stations/sites

I like the interface and format of the data presented, but does not have all the stations/sites that I can easily locate on the web in my area (CO).

New update graphs not updating

Just an FYI to developers. Update on 6/7/16 gauge graphs are stuck at 6/5/16 and app is not fetching graph data. First app I go to on the morning! Great app always recommend to clients
