IWRIS is a Web-based Geographic Information System application that allows users to access, integrate, query, and visualize multiple sets of data from diverse sources.
Some of the databases currently accessible through IWRIS include DWR’s Water Data Library, California Data Exchange Center (CDEC), United States Geological Survey streamflow data, Local Groundwater Assistance Grants (AB303), and data from local agencies. The system will be expanded with additional data sets and functionality in the future.
DWR developed IWRIS to improve water data management and scientific understanding in support of Integrated Regional Water Management (IRWM). The California Water Plan Update 2005 identifies IRWM as a key initiative to ensure reliable water supplies through the year 2030.
