Description

The report is organized into two parts. Part one contains brief technical summaries of methods used to establish instream flow needs determinations in the South Saskatchewan river basin that provide for full protection of the aquatic environment. The purpose of summarizing these techniques within the following document is to provide a basis for the methodology used to evaluate impacts from alternative flow management scenarios. The second part of this document then explains the impact ratings methodology and demonstrates its application using example flow management scenarios applied to seven reaches of the Red Deer River.

Description

Describes the results of the work of a technical team struck to develop instream flow needs (IFN) determinations for all mainstem reaches in the South Saskatchewan River Basin. The team developed an integrated aquatic ecosystem IFN based on fish habitat, water quality, riparian vegetation, and channel maintenance. The integrated IFN determination is presented in a format suitable for input to the SSRB WMP water-balancing model, the Water Resource Management Model.
