The McMurdo Dry Valleys are famous for their lack of ice cover and the strong katabatic winds that blow. But during the summer, it gets warm enough to melt some ice and create streams in the dry valleys. And where there is water to measure, the USGS is there. They even have a couple sites that have real time data online! The below map shows the sites of 20 stream gage sites within Taylor valley.
I just have to include the photograph of someone doing a discharge measurement! Maybe that can be me someday.... :-)
