't I INTRODUC. TION I Section 6.1.3.2. and Appendix E of the Final Environmental Staternent (USNRC 1975) require Phase Two of the aquatic ecology, studies to begin within one week of the start of reservoir fill pumping. Report #1 (McAden et al.
1984) covered the period July 1983 - June 1984, Report #2 (McAden et al. 1985) covered the period July - December 1984, Report #3 (Baker et al. 1985) covered the period July - September 1985. This report presents data for the sampling period October - December 1985, during which time five sets of entrainment and impingement samples were collected.
I METHODS Methods employed in impingement and entrainment sampling in the Colorado River are described in Report #1 (McAden et al.)
I Methods employed in entrainment sampling of the reservoir fill pipelines are I described in Report #3 (Baker et al.)
I RESULTS AND DISCUSSION I
HYDROLOGY AND WATER QUALITY Water temperature, pH, turbidity and dissolved oxygen data from the Colorado River station are shown in Table 1. Conductivity values are given in Table 2, and salinity values are given in Table 3. Water temperature, I

- )
l lI salinity, dissolved oxygen and pH from the Reservoir Makeup Pumping Facility (RMPF) pipeline are given in Table 4 Water temperature, conductivity.
l salinity, dissolved oxygen and pH data from the RMPF re olving screens are given in Table 5.
E A saltwater wedge was present in the Colorado River on 8-9 October, 22-23 October, 31 October-1 Noverber, and 6-7 dovember. On 8-9 October the wedge was within 5 feet of the surface. Heavy rainfall runoff eliminated the wedge for the sample trip of 14-15 November. Aerobic conditions on the river bottom contributed to a higher catch of aquatic organisms in trawls than was evident in previous reports. During 8-9 October sampling, surface water temperatures were higher than bottom water temperatures. However, subsequent samples l revealed bottom temperatures generally higher than surface temperatures.
I Water quality at the revolving screene reflected conditions within five feet of the surface of the Colorado River. Highest salinities were recorded during the 8-9 October sampling, with a maximum of 14.6 ppt on the bottom on 9 l
I October (Table 5). l I The RMPF pipeline also exhibited highest salinity values during the 8-9 October sampling. A maximum salinity of 8.9 ppt occurred on 9 October (Table 4). These data further indicate that water pumped through the RMPF system is drawn from the near-surface waters of the Colorado River.

I I MACR 0200 PLANKTON AND FISH I During the October-December 1985 sampling period 97 taxa of invertebrates and 21 taxa of fish were collected from the Colorado River and 28 invertebrate and 5 fish taxa occurred in saeples from the RMPF pipeline (Table 8).
Tables 9-13, which show the spatial and temporal variations in density of both invertebrates and fish in the Colorado River, indicate that the largest numbers of taxa and the highest densities of plankton occurred at mid-depth and on the bottom rather than at the surface. However, in a night collection on 8-9 October, Callinectes spp. megalopa occurred in very high densities at the surf ace, as well as at mid-depth and on the bottom (Table 9) .
l Oblique samples, which are made in a shallow, shoreline habitat rather than at mid-channel as with the surface, mid-depth and bottom samples, contained high densities of organisms at times but only when the same organisms were also abundant in mid-depth and bottom samples. Examples of I this are Callinectes spp. megalopa and Rhi*hropanopeus harrisii zoeae on 8-9 October (Table 9) and Mysidopsis almyra on 22-?3 October and 31 October-1 November (Tables 10 and 11, respectively). Samples collected at night usually had higher densities of plankton than did samples collected in the daytime, regardless of the depth or location.
In addition to Callinectes spp, megalopa, R_. harrisii zoene and M. almyra, invertebrates which occur md in fairly high numbers in at least some samples include Sagitta spp. (Tables 9 and 11), Daphnia spp, and Simocephalus spp.

u
I I (Table 14), Acartia tonsa (Tables 11 and 12), Labidocera aestiva (Table 11),
Oithona spp. (Table 10), Penaeus setiferus postlarvae (Table 9) and C. sapidus juveniles (Tables 9-11).
I An unusual occurrence of the celanoid copepod, Centropages typicus, was recorded in samples from 8-9 October, 31 October-1 November and 6-7 November (Tables 9, 11 and 12, respectively). These specimens are the first specimens reported from the Gulf of Mexico or its drainage basins and appear to represent a range extension for this species from the east coast of Florida (Dr. Themas Bowman, Smithsonian Institution, personal communications).
I The most commonly collected and numerically abundant fish taxa from the Colorado River were Micropogonias undulatus and Anchoa mitchi g . Various gobies, predominately Gobionellus boleosoma, G. hastatus and Gobiosoma bosci were also commonly collected, although never in large numbers (Tables 9-12).
Fish were taken in very low numbers on 14-15 November (Tabic 13) as a result of freshwater in the study area from heavy rains upstream (Tables 2 and 3).
Tables 14-18 show the -densities of macrozcoplankton and fish taxa in samples from the RMPF pipeline during October and November 1985. Twenty-eight invertebrate taxa and five fish taxa were represented in these samples.
I No single invertebrate taxon dominated samples on all dates, but Callinectes spp. megalopa occurred in high densities on 8-9 October (Table 14). P. setiferus postlarvae were found in low densities in three of the four samples collected on 31 October-1 November (Table 16).

I I Of the five fish taxa collected, only two were taken in moderate to high densities in the RMPT pipeline samples. A_.
mitchilli dominated samples on 8-9 October and 22-23 October with the highest densities being found in night samples (Tables 14 and 15). undulatus dominated the fish taxa in samples M_.
collected on 6-7 November and the highest densities again were found in night I collections (Table 17). No fish were taken on 14-15 November, when the salinity of the water passing through the RMPF pipeline never exceeded 0.2 ppt (Table 4).
I The invertebrates in sa:rples fron the RMPF pipeline were, in general, reflective of the populations occurring in the Colorado River, although the pipeline samples were not as diverse in taxa as the river samples and the densities of a particular taxon were usually lower than in the river.
However, Callinectes spp. megalopa occurred in higher densities in the pipeline than they did in the river during comparable time periods on 8-9 October 1985, the date of their greatest abundance (Tables 9 and 14).
I Although peaks of abundance of both A. mitchilli and M_. undulatus occurred on the same dates in both the river and pipeline, i.e. 6-9 October, 22-23 October and 6-7 November, the densities in the pipeline were considerably lower than in the river (Tables 9, 10, 12, 14, 15 and 17). On 31 October-1 November, when both A_. mitchilli and M. undulatus were abundant in the river (Table 11) they were either absent Q. mitchilli) or present only in very low numbers (M. undulatus) in the pipeline (Table 16).

I I NEKTON I Forty-nine species of macroinvertebrates and fish were caught in seine, trawl and impingement samples (Table 19). Only nine species were common to all three sampling gears. Aerobic conditions throughout the sampling period, accompanied by a decrease in salinity near the end of the period, contributed to an increase in species diversity and abundance over that recorded in Reports #2 and #3.
I Trawls caught seven species of macroinvertebrates and 21 species of fish.
The white shrimp, Penaeus setiferus, was the most abundant invertebrate, and the Atlantic croaker, Micropogonias undulatus, the most abundant fish.
Eight species of maeroinvertebrates and 24 species of fish were collected in the seine samples. The white shrimp was the most abundant invertebrate collected and the Gulf menhaden, Brevoortia patronus, was the most abundant fish collected (Tables 25-29). On 31 October one seine collection was not made due to extremely low tides. On 14-15 November three seine collections were not taken due to high, swift water.
Impingement samples contained seven species of macroinvertebrates, four of which were not caught by trawl or seine, and 10 species of fish, two of which j were nc* caught by trawl or seine (Table 19). The white shrimp was the most l
abundant invertebrate, and the Gulf menhaden was the most abundant fish.

Impingement samples continued to exhibit relatively low species diversity and abundance (Tables 30-34).
