Download or read book Assessment Methods for Aquatic Habitat and Instream Flow Characteristics in Support of Applications to Dam, Divert Or Extract Water from Streams in British Columbia: written by and published by . This book was released on 2004 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications to dam, divert, or extract water from British Columbia streams must be supported by high quality information on hydrology, biology, and habitat from the stream of interest. This document defines assessment methods for identifying impacts on aquatic habitat from water withdrawal. The methods defined are structured into two tiers: those applied at a preliminary (coarse) screening level and those applied at a detailed level. The two-step process is designed to identify projects that pose a low risk to fish & habitat and provides data collection & analysis procedures that should be followed when presenting information to fisheries agency staff as part of an application for a water license. The document describes data requirements for each step: screening (description of the proposed project, hydrology, biology, habitat) and detailed (assessment approach, geomorphology, water quality, fish biology, fish habitat, lower trophic levels, stream & riparian ecology, cumulative effects). An example of a habitat analysis is included. The appendix details the steps of a standardized approach to the collection of instream flow information in relation to fish & fish habitat.
