An excellent East Bay creeks map can be downloaded from here:
Published By: The Oakland Museum of California, 1993, Rev. 1995, Rev 2000.
You used to be able to buy nicely-printed folded copies at the museum store. At least the map is still available as a pdf download.
Also that page has links to webpages with detail sections of a number of creeks.
(I gave them the idea, many years ago, because I didn't have the resources to do it myself. And they followed through! Thank you!)
