Transects were established on Taylor Valley streams during January, 1994. Gage features were positioned at transect sites 1, 2, 3, 8 and 9. Three feature types were observed as follows:  gage box = top center of the surface of the square roof of the wooden shelter housing the gage recording equipment. The "center" was not measured exactly, but an X mark was scratched into the surface of the wood at the point held. gage flume = position of the flume, measured near but not directly at the center of the flume. The reference point is the top  surface of the upper right bolthead of the four bolts securing crossbraces to the top of the flume sidewalls. gage rebar = top of an existing rebar stake, situated midstream, serving as a reference for water measurements at a site without a flume.  By performing an optical topographic survey, the northing, easting,and orthogonal heights were documented for these gage features at Andersen, House, Canada, Delta and Green Creek.
