A Task Committee (TC) of the Surface Water Hydrology Committee was organized in 1976 to determine the types of low-flow information needed, to describe available methods of characterizing low flows, and to identify needed analyses and data collection. Responses to a TC survey of users of low-flow information indicated the need for better estimates of low-flow characteristics at ungaged sites. Available analytical methods are described and evaluated, sources of low-flow information are given, and some recently proposed techniques are reported. Low-flow data on many additional streams are needed.
