Title: River Wissey investigations : linking hydrology and ecology : summary of a recommendations for the River Wissey (OI/526)
Author: National Rivers Authority
Document Type: Monograph
Abstract:
This project provides a detailed examination of the ecology of the River Wissev with specific reference to relationships between flows and the flora and fauna of the river. The river is renowned as a trout stream and the study was commissioned by the National Rivers Authority in 1991. following concerns about the ecological impacts of falling flows. The project had three aims: i) to assess the current ecological status of the Wissev and to place the current situation in an historical context; ii) to evaluate macroinvertebrate-flow relationships for: environmental assessments of flow-related impacts and setting flows to meet in-river needs; and iii) to define a Ecologically Acceptable Flow Regime for the River Wissev on the basis of all available information and approaches. The study included intensive field surveys during 1991 and 1992 (low-flow years) and 1994 (a normal' flow year), supplemented by a comprehensive review of secondary sources.
