OpenStreetMap
Just tracing some water features around what I guess must be the california aquaeduct. Wikipedia is quite a help in discovering the names of some things. Apparently we might have some government data source available for these, which would be better than tracing?

Looks like I'll subscribe to talk-us list then. Is there a sample OSM file for NHD of California? that would be good to compare with the manual tracing...
