Prince William Sound - Places of Refuge

(Photo/Nuka Research & Planning Group, LLC)

This website was used to assist the Prince William Sound Places of Refuge Workgroup in the development of a document describing Potential Places of Refuge in the Prince William Sound (PWS) subarea. A map of the areas of concern within the PWS subarea is shown below.

The PWS Subarea is depicted in the map shown below. Similar projects have taken place for the Aleutian, Kodiak and Cook Inlet Subareas. The workgroup record and products from those projects are available on the PPOR homepage


The objective of this project has been to identify docking, anchoring, mooring and grounding locations that may be selected as Potential Places of Refuge in order to enhance the overall response process.


The map below depicts some of the risk factors used in selecting potential places of refuge. The site assessment matrix (PDF 82K) and site assessment key (PDF 56K) summarize the resources at risk for each site.

Download (PDF 603K) a printable copy of this map. The workgroup has identified a total of 67 PPOR sites. The index map below depicts the 16 different PPOR Maps to be developed to include these sites.

Index of PPOR Maps

A total of 16 maps were created to include the Potential Places of Refuge sites selected in the Prince William Sound Subarea. Each of these 16 pages consists of a map that shows the locations of these sites, along with three tables for each map that give specific information for each individual site. This information includes site considerations, stakeholders, and physical and operational characteristics.

  • Download (PDF 1.8M) a copy of the risk maps used in identifying the PWS Potential Places of Refuge sites.

The following is a list of the PWS Potential Places of Refuge maps identified on the index map with links to the corresponding PDF:

*Note: The grounding site depicted on PPOR Map 04 should not be used based on updated hydrological data information (PDF 456K).

An associated project is the PWS Geographic Response Strategy (GRS) Project.

Invasive Species Considerations

Alien or invasive species include seeds, eggs, spores, or other biological material capable of propagating that species that is not native to an ecosystem. Invasive species commonly are transported in ballast waters and cargo associated oil transport and shipping. During operations any species that are encountered that are suspected to be non-native should be collected and presented to wildlife managers. Additional information on invasive species can be found in the “Useful Websites” section below.
