This paper describes the project to develop a fully automated process to yield highly reliable catchment basins. The most current and detailed BC Provincial Terrain Resources Information Management (TRIM) watersheds with fully connected stream networks are used as the topographic base in the delineation of catchment basins for stream sediment and water sample sites.
