The San Francisco Bay/Sacramento-San Joaquin Delta (Bay-Delta)
The Bay-Delta Estuary covers the confluence of the San Joaquin and Sacramento rivers, and Suisin, San Pablo, and San Francisco bays through which the waters flow to the Pacific Ocean. The Bay-Delta Estuary includes wetlands and sloughs and is inhabited by a variety of fish and wildlife species. While the Bay-Delta is important and unique ecologically, water withdrawn from the Delta provides for much of California's water needs, both for drinking water and agricultural irrigation water. Excessive water withdrawals from the Delta can impact the ecosystem and can diminish the water quality of the remaining water. Because of this, many studies have been or are being conducted in the Delta by various agencies, coalitions, and other groups. The various groups studying the Bay-Delta Estuary have sought to provide a means to share data collected with all interested parties. The World Wide Web interface allows all users with Web access to query the database and includes a Java applet map that provides a brief
overview of data by sampling location. The GIS Avenue interface is available at local workstations. From the Web, the user selects the type of data he or she is interested in such as hydrometeorological, water quality, or biological. The users can pick locations, parameters/analyses/species, and a time frame for the data query. The data meeting the query criteria are retrieved across all studies that have been included in the database. The Web interface was developed using Oracle's WebServer and Java. The GIS interface was developed using ArcView/Avenue.
