Monthly river flow rate data for most of the globe except former Soviet Union countries, which can be found in ds553.1. This compilation was prepared by Byron Bodo (babodo@eol.ca), Jul 2001; it succeeds the Feb 2001 update. This is a combination of datasets from UNESCO, WMO GRDC, the RIVDIS by Vorosmarty (1998), and others. Changes for this version are primarily to documentation, however, there are updates to one Thai and two Bolivian gauges plus replacement of some UK provisional data; details are given in the documentation.

Average record length is about 26.7 years. About 2/3 of the records have from 10-100+ years of data.

The USGS offers the CD-ROM "Hydro-Climatic Data Network: Streamflow Data Set, 1874-1988". This consists of streamflow data measured at 1659 sites throughout the US and its territories. Daily mean, monthly mean, annual mean, minimum and maximum values of discharge are given for each water year. Stations selected distinguish human influences. For more information contact J.R.
