&lt;big&gt;'''The CCoWS Wiki is a student-created resource for information on a range of issues and topics relating to watersheds and ecosystems of California's Central Coast region.'''&lt;/big&gt;

This wiki is an outgrowth of the [[ENVS 560/L Watershed Systems]] class at [http://csumb.edu CSUMB].

&lt;br/&gt;

&lt;big&gt;Some useful starting points can be found in the [[Contents]] page.
