Summary/Recommendations/Objectives:

The 1982 study is the twelfth
yearly survey of biological productivity in

the Conecuh-Escambia Rivers
conducted by personnel of the Department of Fisheries and Allied Aquacultures of Auburn University. Prior to these studies on

the stretch of these two rivers
between Brewton, Alabama and Escambia Bay in

Florida, the Institute of Paper Chemistry of Appleton, Wisconsin had conducted

15 surveys. The primary objective
of these yearly studies is to determine if major

changes
in water quality can be detected from studies of the biota. Plankton,

macroinvertebrates,
and fish populations are sampled at stations above and

below
the Container Corporation of America discharge during periods of low

river
flow. The
results of the 1982 study are summarized in this report. It is noted

that the Conecuh-Escambia River
system was again subjected to major flooding

in the cooler months of 1982, but
the water level during this year's sampling

period
was lower than normal for the season. Sample stations were located in

the
same general vicinity as those utilized in most previous surveys. The

location of all stations sampled
in 1982 are shown in Figures 1 and 2 which

are maps of the Conecuh and
Escambia Rivers. Table 1 provides a description

of each station including
physical and hydrological features of each location.

The mileage index was calculated
using the Brewton Lake outfall as mile 0.0.

Stations upstream of the outfall were assigned
negative distances.
