| Abstract/Description or Keywords |
An Interior Watershed Assessment procedure (IWAP) for the Lopez Watershed is the first phase in a multi-phase project which is currently in progress. Ainsworth Lumber Company Ltd. initiated this IWAP with financial assistance provided by Forest renewal B.C. (FRBC). Other phases of this project include a Sediment Source Survey (active), Terrain Stability Mapping (active), a proposed Riparian Assessment and Fish and Fish Habitat Assessment (1997). All of these assessments are components of an Integrated Watershed Restoration Plan. An Access Management map and Watershed Level and Component Project Objectives should be completed prior to initiating watershed restoration prescriptions and major works. The IWAP was designed to assist forest managers in determining the type and extent of hydrological related conditions within the Lopez Creek Watershed (east of the North Thompson River) and to identify any water related concerns with respect to planned and future forest developments. Assessment of hydrologic impacts focused on: (1) The potential for change to peak flows (2) The potential for mass wasting (3) The potential for accelerated surface erosion (4) The anticipated changes to the channel riparian buffer. These impacts were assessed following the IWAP Guidebook, Level 1 analysis, September 1995. watershed assessment, watershed management |
