Welcome to CDEC A division of DWR

Alternative Access to CDEC

There are various ways to access CDEC data and products. If you're reading this page, you may already know about accessing CDEC data and products through the CDEC Web site, the access point to the Department of Water Resources' operational hydrologic database. But did you know that you can also get CDEC data and products through an alternative Web site for government and cooperating agencies, or in the case of an emergency, through a CDEC Dial-up Account?

CDEC Intranet

If you are a member of a government or cooperating agency, you are eligible for access to the CDEC Intranet Web site. With CDEC Intranet access, you have dedicated and direct access to all data and products maintained by the California Data Exchange Center. And you won't have to compete with public users during peak times who are also accessing CDEC data and products. All data and products available on the public CDEC Web site are available through the CDEC Intranet site.

To obtain CDEC Intranet access, please send your request to webmaster@flood.water.ca.gov. In order to process your request for CDEC Intranet access, you will then be asked to provide certain information.

CDEC Dial-Up Account

In addition to CDEC Intranet access, sign up now for a CDEC dial-up account. A dial-up account will allow you to connect directly with our computers should there be any problems getting connected to the Internet via your network or through your Internet service. CDEC dial-up accounts are provided FREE of charge. However, you will only be able to retrieve CDEC data and products, not items on other Internet Web sites.
