National Wildlife Refuge System


What is the Water Resources Inventory and Assessment (WRIA)?
The Water Resource Inventory and Assessment (WRIA) is a database housed on the Environmental Conservation Online System (ECOS). It stores and retrieves existing water resource information, including geo-spatial data, for the entire Refuge System. Information is entered for individual refuges regarding water features, monitoring, water quality, water rights, water-related infrastructure and hydro-climate. WRIA also stores information on a refuge’s water-related needs and threats. A WRIA provides a professional assessment of a refuge’s water resources, including needs and threats as well as recommendations to address specific issues.


U.S. Fish and Wildlife Service staff can easily retrieve water-related documents from the integrated ServCat database. In the future, WRIA and PRIMR will be integrated to link comprehensive information on water surveys within refuges.


Upon completion of a WRIA, refuges are provided with a document summarizing inventory data.  This professional assessment of the refuge’s water resources, including needs and threats, offers recommendations for identified issues.


Who benefits from the WRIA initiative?
The ultimate beneficiaries are the plants, animals, and habitats supported by improved water resource management on national wildlife refuges. Inventory information recommendations specific to individual refuges and field stations can be found in the summary document. The WRIA database can be queried and data aggregated by regional and national offices to identify trends and prioritize work based on needs and threats. The WRIA initiative has been designed to provide useful information to multiple users.


Who is conducting WRIAs?
WRIAs are being conducted by regional hydrologists who provide professional assessments and prepare narrative documents. Regional personnel work closely with refuge staff throughout the WRIA process to ensure an accurate and useful product.  Funding is provided by the regional and national Inventory and Monitoring initiative.
