DFLOW is a computer program for estimating design stream flows for use in water quality studies. The manual describes the use of the program on both the EPA's IBM mainframe system and on a personal computer (PC). The mainframe version of DFLOW can extract a river's daily flow record from EPA's STORET system and convert it into a format suitable for downloading to a PC. Both the mainframe and PC versions can compute aquatic life design flows based on either continuous duration or annual extreme value flow statistics and a human health design flow equal to a river's harmonic mean flow. The manual also describes the computational methods employed by DFLOW.
