Water Resource Inventory Areas are Washington State management regions that do not strictly follow watershed boundaries.
Maps and GIS
ERMA map layer list
The Puget Sound Institute is collaborating with NOAA's Office of Response and Restoration to enhance map layers and GIS data on NOAA’s Environmental Response Management Application® (ERMA) site. Below you will find a catalog of current NOAA-generated map layers that have been indexed and made searchable within the Encyclopedia of Puget Sound. The links will take you to the corresponding layers within ERMA, or you can simply visit the ERMA Pacific Northwest website directly to search more broadly.

More information
Geographic information systems play an increasingly important role in data collection and analysis in Puget Sound, with much of this data finding its way online. The Internet is now awash in geospatial information, something that presents both opportunities and challenges. How do we sort through what's out there to find what we need? Is there a way to bring some of this far flung data together in one place? Further, can we democratize the data? Can we offer sophisticated geospatial information to scientists or policymakers who may or may not be GIS experts, or may not own expensive GIS software?
The PSI role
In response to these challenges, the Puget Sound Institute (PSI) and the Encyclopedia of Puget Sound are collaborating with NOAA's Office of Response and Restoration to enhance a new mapping application focusing on the Puget Sound and Salish Sea ecosystems. The effort will ultimately bring together thousands of map layers on NOAA’s Environmental Response Management Application® (ERMA) to improve access to regional geospatial data and research.
NOAA has been testing and developing a Puget Sound version of ERMA internally as part of its Climate Assessment and Proactive Response Initiative (CAPRI), including a pilot study of impacts of climate change and sea level rise on contamination sites within Puget Sound. Through ERMA, NOAA and its partners have created an intuitive, fast and robust mapping system accessible to anyone with a computer and an Internet connection. NOAA has already brought together a large selection of map layers from many federal, state, regional and local agencies, as well as analytical tools— such as ESI and IPaC query functions— and real time monitoring capabilities.
The Puget Sound Institute began working with NOAA in late 2011 to pull together additional maps related to a wide variety of spatial frameworks, ranging from hydrology and Puget Sound Basin characterization to occurrences of invasive and threatened species. Eventually, the Institute will also enlist the wider scientific community to suggest or offer maps for inclusion.
