Flow Guidelines for Instream Values

May 1998, Ref. ME270 (Volume A) ME271 (Volume B)

These guidelines provide a consistent approach to setting minimum flows and other flow requirements in rivers. Volume A covers the principles of hydrology and hydraulics, discusses various instream values, and sets out by the process by which flow requirements are determined and given practical effect. Volume B provides technical and background information.
