About the SWIM Digital Atlas

For years SRWP has been working towards providing a watershed resource library to address the information needs of its stakeholders. Early on it was determined that this would best be accomplished by providing a virtual resource center through the SRWP web site. In 2007 SRWP took a significant step towards that goal through the launch of the Sacramento River Watershed Information Module (SWIM).

The SWIM Project started in 2006 with seed funding from SRWP's U.S. Environmental Protection Agency grant. Since 2007, the project has been expanded through a CALFED Watershed Program grant, and now by DWR's Integrated Regional Water Management (IRWM) process.

SWIM is currently being used by the CABY and Upper Pit River Integrated Regional Water Management Groups to manage data, documents, and photographs generated by these collaborative planning efforts. Also SRWP is in the process of adding integrating content from the Roadmap Project into the SWIM Atlas.
