         WQ: Phosphate (Total) in Americano Creek/Estero Americano 1988-1990 | 
     
 
 
    | 
   Caption:  The graph shows average, minimum, and maximum total phosphate concentrations measured in Americano Creek, and its estuary, Estero Americano, during 1988-1990.  Sampling occurred generally monthly, with the number of total phosphate measurements at each station ranging from 17 to 30 samples for the monitoring period.  Note that Stations E-1 through E-5 are estuarine.  Some total phosphate measurements were below the minimum detection limit (MDL), and therefore half of the MDL was reported for that value.  This monitoring was part of a water quality study of Americano and Stemple Creeks by Merritt Smith Consulting for the City of Santa Rosa and U.S. Army Corps of Engineers.  See Picture for a map of the sampling locations and Info Links for more details.
