Other DWR Portals

DWR provides water data and information on other portals and web applications. See links below:

California Data Exchange Center

The California Data Exchange Center (CDEC) installs, maintains, and operates an extensive hydrologic data collection network including automatic snow reporting gages for the Cooperative Snow Surveys Program and precipitation and river stage sensors for flood forecasting.

Open Data

The Open Data Portal is a new repository of water-related data sets. The data sets are available for download. 

California Irrigation Management Information System

The California Irrigation Management Information System (CIMIS) is a program unit in the Water Use and Efficiency Branch, Division of Statewide Integrated Water Management, California Department of Water Resources (DWR) that manages a network of over 145 automated weather stations in California. CIMIS was developed in 1982 by DWR and the University of California, Davis (UC Davis). It was designed to assist irrigators in managing their water resources more efficiently. Efficient use of water resources benefits Californians by saving water, energy, and money.

California's Groundwater Live

California’s Groundwater Live application provides powerful new tools for users to view, interact, and analyze the latest groundwater information in an open and transparent platform.

Water Data Library

The water data library provides geographic-based data on water conditions.

SGMA Portal

This portal allows local agencies, groundwater sustainability agencies (GSAs), and watermasters to submit, modify, and view the information required by the Sustainable Groundwater Management Act (SGMA), and enables the public and interested stakeholders to view submitted information and provide comments, where applicable. No login is required for public access.

CASGEM Online System

As a result of SBX7 6 (enacted in November 2009), DWR developed the California Statewide Groundwater Elevation Monitoring (CASGEM) Program to make groundwater monitoring information available to the public through a collaboration between local monitoring parties and DWR to collect groundwater elevation information statewide.

Online System for Well Completion Reports (OSWCR)

California Water Code Section 13751 requires that anyone who constructs, alters, or destroys a water well, cathodic protection well, groundwater monitoring well, or geothermal heat exchange well must file with the Department of Water Resources a report of completion within 60 days of the completion of the work. Drillers submit their well completion reports with the Online System for Well Completion Reports (OSWCR, say "Oscar"). OSWCR users create an account based on their C-57 license, which DWR will validate. Upon approval, users will be able to submit Well Completion Reports.This online system replaces DWR Form 188. 

GIS Mapping Sites:

Flood Emergency Response Information Exchange (FERIX)

The Flood Emergency Response Information Exchange (FERIX) provides participating agencies an online system to access and exchange current flood information in real-time through Web GIS interface. It integrates geo-referenced databases, a real-time data collection and exchange system, and a decision support system supporting other DWR programs, various hydrologic and hydraulic computer models and tools, and applicable flood-related documents.
