I. INTRODUCTION The present survey includes a series of samples taken on Choccolocco Creek and its tributaries during October, 1969Stations utilized are indicated on the maps appended to this report. The objectives of the survey were:
(1) to obtain Fall samples of the various fish species,
(2) to enhance our general knowledge rele vant to the total fish fauna of the system,
(3) to determine water quality during the Fall at our regular stations utilized for past surveys,
(4) to study the bottom types, depth and bank configurations of the stream, and
(5) to obtain fresh samples of fishes, other . vertebrates and invertebrates upon which Monsanto Company personnel may perform residue analyses.

H. METHODS
'
f-
The methods utilized for water quality work and the collection
of fishes are the same ones employed in previous surveys with two
exceptions. Turbidity and color analyses were made using a Hach
Chemical Company direct-reading colorimeter. Turbidity is
measured in Jackson Turbidity Units (J. T. U.) using this instrument
and color is measured in "apparent color units. "

m. WATER QUALITY
The usual ten (10) water quality stations were utilized as
follows (see maps):
(1) Highway 78 bridge above Anniston
(2) Boiling Springs above treatment plant m? (3) Bridge below treatment plant
c-i*. (4) Highway 21 bridge
ri-
(5) Highway 109 bridge crossing
(6) Highway 93 bridge crossing
(7) Highway 77 bridge crossing
(8) Stemley bridge
(9) Dry Creek below Coldwater Spring, Highway 78, and
-
(10) Snow Creek at Highway 78 bridge
Water temperature in Choccolocco Creek, stations 1-7, ranged
from 66-67 F; at Stemley Bridge the water temperature was 71 F
(see table). At stations 9 and 10 in the tributaries the water temperature
range was 65-66F. All of these temperatures are within the normal
range to be expected at this time of the year.
Hydrogen-ion concentration ranged from 6. 6 to 6. 9. The pH
value for'station 10, Snow Creek, is listed as "Interference" in the
table since pH determinations were made in the field using the colorimeter.

A sample of water was returned to the laboratory and checked with a Beckman pH meter; the result was 5. 9. We cannot be certain that this pH value is truly representative of conditions in Snow Creek on October 15, 1969, since pH may change in water samples after a few days' time has elapsed.
Dissolved oxygen levels were quite satisfactory at all stations in terms of generally accepted water quality standards except at station 4 in Choccolocco Creek at the Highway 21 bridge station. The depression in dissolved oxygen level to 4. 3 mg/1 (see table) is surely due to sewage from the treatment plant and is not unexpected.
The high total acidity (free CO^) value for Snow Creek (see table) would prevent fishes from occurring there. Fishes cannot tolerate total acidity values much in excess of 20-25 ng/1. The total acidity value of 26 mg/1 at station 3 is, of course, a reflection of the situation at station 10, as is the value of 13 mg/1 at station 4. The decrease in total acidity in Choccolocco Creek as the water passes downstream is due, of course, to dilution by a larger volume of water in the mainstream.
The alkalinity values (see table) are of no particular biological signi ficance. Suffice it to say that the values are high enough to permit a reasonable production rate for the plankton organisms present in Choccolocco Creek.

Turbidity was quite low, in the vicinity of 10-15 Jackso,n Turbidity
Units for the most part- The high determination at station 3 represents
the effect of the high color of the water coming in from Snow Creek (see
table) -
-
The high color reading for Snow Creek probably resulted from
. unusual conditions that prevailed temporarily as a result of the strike
and consequent shutdown of Monsanto Company. Regulatory agencies
would have found a value in excess of 500 color units for Snow Creek to
be unusually excessive. However, this was obviously a temporary situation,
since the brilliant yellow-green color that prevailed in Snow Creek on
October 15, 1969, was not at all evident on October 17, 1969, when the
tributary was re-examined in this regard.
In biological terms, the only water quality characteristic that would
clearly be a limiting factor for fishes would be extremely high total
acidity values for Snow Creek.

IV. Fishes
A. Fish collections for Choccolocco Creek proper
The locations of the collecting sites are described in Table 2
and indicated on Fish Station Maps 1 and 2.
A collection could not be made at station #9 site because the
reservoir was backed-up and had the entire collecting area flooded.
Although this one site was omitted two new sites were sampled. The
upstream site, designated as station =4-A, is at the covered bridge
crossing 6. 6 miles southeast of Oxford. This is an important addition
because it is closer, on the upstream side, to the outfall area at Oxford
than station #4 at Hwy 78 crossing. Perhaps with some additional scouting
in the stretch between station #4-A and the outfall we may be able to get
even closer. However, we believe that the habitats at both site #4-A
and #4 are similar to those that formerly existed at the outfall area.
The other additional collecting site, #8-A, is at Jackson Shoals.
We were somewhat disappointed because we expected more variety and
more individuals than what we obtained. (Table 3). Jackson Shoals has
the general physical appearances of a rich environment but was poor on
yield by our sampling methods.
A total of 3, 787 specimens was obtained from the eleven, stations
in comparison to 5, 025 specimens for ten stations during our January,
1969 survey. Note the paucity of species and specimens at stations #5
DSb 103074
STLCOPCB4022641
8
and #6. Actually the sample for station #5 was taken from two '*
isolated pools and is not representative of the population in flowing part of stream. Repeated attempts in the stream itself yielded nothing, no fishes and no invertebrates.' Obviously some of the forms that we collected from the isolated pools were ones that had moved into the area during high water and then became stranded when the stream receded. There is a progressive trend of recovery as evidenced by samples from stations #6 through =8.
The eleven stations yielded a total of 50 species versus 48 species during the January, 1969 survey (Tables 3 and 4). Catches were similar for most sites but one exception was at station =4 (Hwy 78 crossing). During this survey we were able to sample a riffle downstream from our past collecting area. This riffle yielded several additional species that we had not recorded from the station during former surveys.
We added one more tributary collecting site, tributary station #2-A. This collecting site is located on the lower part of Shoal Creek, just a few miles above its junction with Choccolocco Creek. This site yielded the greatest number of species (25) of any tributary collection (Table 5).
With additional surveys and additional collections from new sites we will be able to graph the productivity trends for the relatively unaltered portion of the Choccolocco system and also for the altered or polluted part. Our data expressed in terms of number of species and specimens in our samples are indices and not actual productivity figures.

VI. Discussion
'*
Our past surveys and the observations recorded above continue
to support our views as presented in the previous report; the Chocco-
-locco immediately below the Anniston Sewage Treatment Plant has
been and is being affected by pollutants. Repeated attempts to collect
in flowing channel of Choccolocco Creek at Hwy 21 yielded no fishes and
no macroinvertebrates. The relatively few animals taken were existing
in isolated pools.
We found additional deformed fishes particularly at Hwy 95 crossing.
However, reproduction had occurred in a number of forms because we
took many juvenile and young of the year specimens.
As in our previous report we strongly recommend at ieast one
additional survey during March or April or perhaps as late as May being
that our first survey (May) was during unusual high water conditions.
The main purpose would be to obtain samples from the nearby tributaries
of the Coosa (Logan Martin Lake). We need these samples (as explained
previously) for comparative purposes and to determine if Choccolocco
Creek is the focal site for the fish deformities. By comparative we mean
a determination of the gradient of fish species occurring between the
headwaters and the reservoir. During this survey we would continue
