As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor the glacial meltwater streams in the region. Measurements are regularly made to examine water quality, quantity, and chemical properties. The stream gauge and outlet locations table serves as an index of the sampling points used to collect hydrological and stream chemistry data in the McMurdo Dry Valley network of streams.

This data package includes shapefiles for selected glacier, stream watershed, and stream channel boundaries in the McMurdo Dry Valleys region of Antarctica. A combination of satellite imagery and digital elevation models were used to delineate watershed and stream channel outlines, while glaciers were outlined by hand. Watershed boundaries provide an estimate of the overall topographic contributing area for each stream in Fryxell Basin, whereas stream channel boundaries provide a topographic area estimate for stream channel, beyond the wetted margin, for each stream.
