Description: Beginning in 1983, the Northwest Power Planning Council (Council) directed extensive studies of existing habitat and has analyzed alternative means of protection. In 1988, the Council concluded that: 1) the studies had identified fish and wildlife resources of critical importance to the region; 2) mitigation techniques cannot assure that all adverse impacts of hydroelectric development on these fish and wildlife populations will be mitigated; 3) even small hydroelectric projects may have unacceptable individual and cumulative impacts on these resources; and 4) protecting these resources and habitats from hydroelectric development is consistent with an adequate, efficient, economical, and reliable power supply. The Council, relying on these studies, designated certain river reaches in the basin as "protected areas," where the Council believes hydroelectric development would have unacceptable risks of loss to fish and wildlife species of concern, their productive capacity or their habitat. River reaches to be protected are those reaches or portions of reaches listed on the "Protected Areas List" adopted by the Council on August 10, 1988, and subsequently. For each river reach listed on the Protected Areas List, the fish and wildlife to be protected are those on the list. This dataset represents the StreamNet project's attempt to georeference the information from the protected areas list to the PNW 1:100k scale River Reach Hydrography (http://www.streamnet.org/pnwr/pnwrhome.html) on the LLID-based stream routing system. Due to limitations in the original source scale (modified 1:250k) and methods used to identify map features, not all protected areas could be resolved to the 1:100k hydrography. Typically, river reaches were not resolved for one of three reasons: 1) the reach depicted does not exist on a 1:100,000 scale map, 2) there was insufficient information in the Protected Areas database to confidently place the location of the reach on a 1:100,000 scale map, or 3) the database depicted the location inconsistently (ie., it overlapped with other information, or was othewise not logical). A list of protected areas that could not be resolved is available from ftp://ftp.streamnet.org/pub/streamnet/ProtAreasDownload/Unresolved_ProtAreas.zip If you have additional information on any of the unresolved protected areas, please contact the StreamNet project at StreamNetGIS@psmfc.org The StreamNet project (http://www.streamnet.org) is a cooperative venture of the Pacific Northwest region's fish and wildlife agencies and tribes. StreamNet is managed by the Pacific States Marine Fisheries Commission as a component of the Northwest Power and Conservation Council's Fish and Wildlife Program. The project is implemented through a partnership involving the states of Idaho, Montana, Oregon and Washington along with the Columbia River Inter-Tribal Fish Commission and the US Fish and Wildlife Service. Funding is primarily through the Bonneville Power Administration (BPA Project No.: 198810804) with occasional support from the EPA and NMFS.
