East Marin-Sonoma SUB BASINS:

Outlines of Sub Basins were produced from aggregating Calwater Planning Watersheds V 2.2.  Sub basins were designed to frame the natural drainage systems within the hydrobasin.  One exception to this relates to the Calwater Planning watershed named Gallinas Creek, which in fact, crosses 2 naturally occurring watersheds, Novato Creek and Miller Creek.  Thus, in order to be in aggreement with Calwater V2.2, it was necessary to ignore these 2 natural drainages when producing the sub basins.
