The Taylor Valley Streamflow Volumes table was created by Harry House. It was first stored in an INGRES database, but was converted to ORACLE format in early 1996. Modifications were generally made each year after the initial creation in the early part of the year. It was transferred to INSTAAR in late 1997. In March, 2000, Denise Steigerwald added a 'dataset code' variable to this file in order to make the dataset more useful in Oracle and GIS.
