About the Map Maker

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.

SWIM will become a key feature of SRWP's web site by providing an online database of maps, GIS coverages, documents, photos and other resources that will be searchable through an online map interface.
