started on Perdido River at Barrineau Park. The collection of river
stages on the Escambia River near Gonzalez was started in 1951 and
streamflow records on Pine Barren Creek near Barth were started in
1952. Streamflow data were also collected at two nearby sites, Yellow
River near Holt (1934-1940) and Escambia Creek at Flomaton, Ala-
bama (1939-1951).
 At the start of the present investigation in 1958, additional data-
collection sites were established to define streamflow conditions and to
determine in more detail the quantity and quality of the water supply
in the area. A list of data-collection sites and the length of record at each
site are given in figure 15. The map in figure 16 shows the location of
these sites.
