| Abstract/Description or Keywords |
The level 1 IWAP is an office-based reconnaissance level investigation with the objective of identifying potential impacts of road building and forest harvest on watershed resources. The Hurley River watershed is located approximately 65 km west of Lillooet, B.C. Hurley River is a tributary of Bridge River, and is thus part of the Fraser River drainage basin. The level 1 IWAP is an office-based reconnaissance level investigation with the objective of identifying potential impacts of road building and forest harvest on watershed resources. All information gathered for the level 1 analysis is taken from existing maps, aerial photographs and reports, supplemented with telephone interviews with persons familiar with the area. The procedure indicates which areas within a watershed are at risk from forest harvest, and helps guide recommendations on follow-up field work (i.e. Level 2 assessments), as required. Specific objectives for the Hurley River IWA are to: 1) Delineate sub-basins in the Hurley Creek watershed; 2) Compile 11 watershed indicators for each sub-basin from measurements made from maps and aerial photographs; 3) Calculate hazard indices; 4) Evaluate hazard sensitivity based on the hazard indices values and the quality of information used to generate the indices; 5) Make recommendations for further watershed assessment work. watershed assessment, sediment, erosion, peak flow |
