Fish Passage GIS Analysis Version 2...
One of the first challenges for the FPTWG was to quantify the size of the fish passage problem in BC. To define the magnitude of the problem and help guide prioritization of Fish Passage field activities, Version 1 of the Fish Passage GIS Analysis was completed in 2008. Using the Corporate Watershed Base (CWB) and other sources, a model was created to generate two primary outputs: 1) the extent of potential fish habitat on all BC streams, and 2) the location of road crossings likely to be culverts on these streams. Culverts are closed bottom structures and are the type of structure most likely to represent a barrier to fish passage. The modelled culverts were then classified as being on potentially fish bearing or non-fish bearing streams and indexed in order of priority for Fish Passage assessment and/or repair based on their position on the stream network.
