Existing and Potential Hydropower projects.
Locations of existing and proposed hydropower sites in the Pacific Northwest
The Pacific Northwest Hydropower Database is part of the Pacific Northwest Hydropower Database and Analysis System (NWHS). The NWHS was developed by the North Pacific Division of the U.S. Army Corps of Engineers (COE) in cooperation with the Northwest Power and Conservation Council (NPCC) and the Bonneville Power Administration (BPA).

Identifies a project as an independent project or as an alternative (dependent project) to some other project proposal. This item also indicates which one of the possible alternative projects should be included in estimates of total regional potential. Dependent projects are those that compete for the same physical location or water source such that the construction and operation of one would preclude or exclude the construction and operation of the others. Independent projects are those whose construction and operation would not compete with any other project in terms of location or source of water. Assigning each project one of three codes indicates project dependency. These codes are "I" (independent), "D" (dependent or competing project which is determined to be the "best" alternative proposal for site development), and "E" (dependent or competing project which excluded from development by a "better" alternative).
Independent project whose development and operation would not adversely impact upon the development or operation of any other project. Also may include a project that would be operated together with other projects as a system.
Project whose development and operation would adversely impact upon the development and operation of another project. A project in this category is the project that is considered to be the best alternative among all projects competing for use of a site (physical location).
Projects whose development and operation are precluded by a category "D" project. Theoretical power potential available through development of these projects will not be included in summaries of regional power potential.

Date of current status.
For FERC projects the date of the current status (Item 218) is the date on which FERC issued the notice or order, which established the current status. Normally this date is shown in parenthesis immediately under the title of the order of notice. (This date may be different from the "effective" dates entered in previous items.) For Federal projects, the initial date will be the date when the data form was completed. This date will be revised periodically as required by changes in the status of these projects.

The information depicted in this GIS layer is the result of digital analyses performed on a database consisting of information from a variety of governmental and other credible sources. The accuracy of the information presented is limited to the collective accuracy of the database on the date of the analysis. The information is believed accurate and reasonable efforts have been made to ensure the accuracy of the data. However, the Bonneville Power Administration GIS expressly disclaims responsibility for damages or liability that may arise from use of this data. This product is the property of the Bonneville Power Administration GIS and its use is thereby restricted.
