Bibliographic Resources concerning the Klamath and Trinity Rivers.


The Klamath Resource Information System (KRIS) was initiated in the Klamath and Trinity river basins to track fishery and water quality and restoration trends. Version 1.0 for the Klamath-Trinity was completed in February 1998 and Version 2.0 in April 2001. The Trinity County Resource Conservation District (RCD) is responsible for production of Version 3.0, which was funded through the Trinity River Restoration Program.

Contributions of data, photos and map information from the agencies, Tribes, non-governmental organizations and basin residents were overwhelming. The Cooperators in this project recognize the need to use applied science to protect and restore the health of the Klamath River. They also believe that shared science can be used to build trust with their neighbors. Contact the Trinity County RCD to get CD copies of the database.
