CalWater - Watershed Boundaries
CalWater is a spatial dataset of watersheds in California, developed by an Interagency Watershed Mapping Committee (IWMC). For many years, the Natural Resources Conservation Service and other State and Federal agencies, have been working with this committee to map the watersheds and hydrologic units in the State of California. This web site documents the history and current status of this interagency effort.

Watershed Management Council
The Watershed Management Council is a non-profit organization whose members represent a broad range of watershed management interests and disciplines. Membership includes professionals, students, teachers, and individuals whose interest is in promoting proper watershed management.

Bay-Delta and Tributaries Project
The Bay Delta and Tributaries (BDAT) Project contains environmental data concerning the San Francisco Bay-Delta and provides public access to that data. Over fifty organizations contribute data voluntarily to this project. The database includes biological, water quality, and meteorological data. These can be used to gauge the health of the estuary and to manage water and environmental resources.

CALFED Watershed Program
The Watershed Program was established in 1998 as an aid to achieving the overarching goal of the CALFED Bay-Delta Program to restore ecological health and improve water management by working with the community at a watershed level. The goals of the Watershed Program are to provide financial and technical assistance for watershed activities that help achieve the mission and objectives of CALFED, and to promote collaboration and integration among community based watershed efforts

Surface Water Ambient Monitoring Program (SWAMP)
SWAMP is a statewide monitoring effort designed to assess the conditions of surface waters throughout the state of California. The program is administered by the State Water Resources Control Board (SWRCB). Responsibility for implementation of monitoring activities resides with the nine Regional Water Quality Control Boards (RWQCB's) that have jurisdiction over their specific geographical areas of the state. Monitoring is conducted in SWAMP through the Department of Fish and Game and US Geological Survey master contracts and local RWQCBs monitoring contracts.

The California Biodiversity Council (CBC)
The California Biodiversity Council (CBC) was formed in 1991 to improve coordination and cooperation between the various resource management and environmental protection organizations at federal, state, and local levels. Strengthening ties between local communities and governments has been a focus of the Council by way of promoting strong local leadership and encouraging comprehensive solutions to regional issues.

The California Legacy Project
The California Legacy Project is an exciting new initiative that involves a broad range of government agencies and citizen organizations. Working together, we are developing a new suite of tools and maps to help us make the important decisions about conserving and protecting California's many landscapes and its magnificent natural legacy.

Natural Resource Project Inventory (NRPI)
A Collaborative Effort between the California Biodiversity Council and the University of California at Davis Information Center for the Environment. The signatories of the California Biodiversity Council joined forces to gather information on thousands of conservation, mitigation and restoration projects being developed and implemented throughout California. The result, the Natural Resource Project Inventory (NRPI), has become a comprehensive electronic database searchable on the Internet.

California Watershed Assessment Manual (CWAM)
In California, many watershed assessments are conducted to guide restoration planning, water and land management decisions, and various land uses. Oregon has a manual to guide watershed assessment, but California does not. So, to assist watershed groups, local agencies, private landowners, and watershed specialists in assessing watershed condition, the State of California is developing the California Watershed Assessment Manual (CWAM).

California Watershed Network
The Mission of the Watershed Network is to help people protect and restore the natural environments of California watersheds while ensuring healthy and sustainable communities.
