This photo shows Greg Radcliffe in the bottom of the Greensboro gauge house where he was able to thread the ISCO 6700 Sampler intake tube through a pipe and out into the stream where Tom secured the tube to the end of the pipe so that it would be positioned properly to take water samples. As you can see there wasn't much room down there...which proved helpful in this case as Greg did his best to balance himself against the walls and prevent himself from falling into the spiders on the wall or into the murky waters below.
