Investigate Newport Bay with CalSWIM

CalSWIM is a new watershed information and management tool designed both as a public forum for exploring local watersheds and as a web location for professionals to acquire data and to interactively model watershed changes. Currently, the CalSWIM prototype provides detailed environmental information about the Newport Bay watershed of Orange County in southern California.

CalSWIM is an ongoing project with the visionary goal of developing a protocol and standard that can be applied to any watershed, facilitating coordinated, integrated, and informed management decisions for those in the water resources profession.

This site provides a web-based GIS explorer for interacting with watershed geographic and hydrologic features including links to data available through the project sponsors. You will also find data capable of being queried and downloaded as well as an interactive model of Newport Bay that plots water quality changes with input variations.

CalSWIM is sponsored by the Orange County Storm Water Program and the University of California, Irvine, Departments of Engineering and Informatics. Technical assistance has been provided by the University of California Cooperative Extension, TetraTech, Inc and Dr. Brock Bernstein.
