Historic DOQs



Production of historical DOQs (made from 1948 and 1953 aerial photos) for the 

San Francisquito Creek Watershed was initially prompted by a need for an analysis 

of land cover change. The land cover change data will be used in a sediment model 

of San Francisquito Creek. The sediment model will help people decide how the 

creek should be managed for flood control, water quality, and steelhead habitat. 

The historical DOQs will also be useful for other geographical and historical studies 

of the San Francisquito Creek Watershed area.
