DAMOS is the culmination of nearly a decade of prior study efforts, actually preceding NEPA, which have been directed towards the understanding of the effects of and the responsible management of the ocean disposal of dredged materials in New England waters as they fall under the authority ot the New England Division of the Corps of Engineers. The individual site reports hence- forth will be updated approximately on an annual bases as additional knowledge is gained, at least with respect to those sites where signifi- cant disposal activities will have occurred. WESTERN LONG ISLAND SOUND Disposal ~f dredge spoils from harbors in the Western Long Island Sound area has taken place at the Cable and Anchor Reef site (Fig. I-1) since the beginning cf the twentieth century. A rough estimate of 10 million cubic meters of spoil had been dumped at this site through 1973, most of which resulted from maintenance dredging of surrounding harbors. This site has become a major lobstering area and therefore, no longer suitable for future disposal of spoils. An alternative to the Cable and Anchor Reef site has been proDosed by a combination of state and federal agencies in a depression two miles east of the original area. This Western Long Island Sound disposal site (Fig, I-2) is being studied as part of the DAMOS program to provide background data should a requirement for a disposal area arise in the future. Meanwhile, a somewhat reduced monitoring effort will be conducted at the Cable and Anchor Reef site to provide continuity for long term effects. Bathymetry The first survey of the Western Long Island Sound disposal site was conducted on February 8 and 9, 1978, (Fig. I-3(a-h)). This survey confirmed the presence of a depression with a maximum depth of 50 meters, however, it was apparent that the major axis of the depression was east-west, while the survey was oriented north-south. Therefore, the second survey, on July 25, 1978, (Fig. I-4(a-m)), was altered such that the north-south lanes were shortened and increased in lumber tc provide more coverage in the east-west direction. This survey provided better de ip*ion of the depression, indicating a steeper slope on the northern margin and more gentle. uniform slopes on the southern side.

INOW NY3SLSoM' HILYON observation made during this survey, that eventually caused the reiection of this site as a potential disposal area, was the presence of many lobster trawls along the northern slope of the depression. Bathymetric surveys were conducted at the Cable and Anchor Reef site on February 9, 1978 (Fig. I-5(a- )), and on duly 26, 1978 (Fig. I-6(a- )). The Predominant features on these surveys were the steep slope toward Cable and Anchor Reef on the eastern edge of the area, a NE-SW trending mound on the north- east section of the site and a circular mound in the western section. All fea- tures are repeated on both surveys, however, the size of this site compares with that of Bostcn Foul Ground and Lightship and detailed comparisons of contours are prohibited because of the scale factors involved. Currents Two sets of current meter data have been obtained at the proposed Western Long Island Sound disposal site, the first from April 12 to July 1, 1978 (Fig, I-7(a-d),.Table I-1), and the second from July 26 to September 7, 1978 (Fig. I-8(a-c), Table I-2). A similar record was also obtained at the Cable and Anchor Reef site from April 1] to May 20, 1978 (Fig. I-9(a-c), Table I-3), although there are recording problems for the first twelve days of the record. The two records from Western Long Island Sound cover the same period of time that data were obtained at New Haven and exhibit similar characteristics in that greater eneray is present in the second record and the effects of a storm surge can be seer in the data. In this case, however, the major increase in kinetic energy is not restricted to the residual component but includes tidal eneray as well. sinnieicantlys the ratio of tidal energy to total energy is ascent for both series of data. eh CSAWQ) SHIL LAU AANA KAA 33S/H> @ = IMAUSINI @33¢5 g 3 in (235/W>) Q33d5 3Z = TWAMBINI § BL 711d Le OL BL 718d Zi ONNCS GNHIS!

At New Haven, the effect of the storm could be seen throuah two tidal cyctes while in this set of data a single peak of 65 cm/sec was observed, that is more than twice the average maximum speed. 4t the Cable and Anchor Reef station, located approximately 2 NM west of the Western long Island Sound Station, the currents are significantly less. ,«Thet 10% highest speeds at Western Lona Island Sound are on the order of 40-45 cm/sec while at Cable and Anchor Reef, they are only 30 cm/sec. It should be noted, however, that the tidal kinetic energy less the mean current results in similar values of 109 dynes/sec and 106 dynes/sec respectively for the same period of time. Residual and mean current components are substantially lower for the Cable and Anchor record. It is interesting that no indication of the anomalous high current veloci- ties caused by the storm at New Haven and Western Lonc Island Sound are present at Cable and Anchor Reef. The higher velocities were all directed westward, hence, the meter at this site may have been in the lee of shoals east of the mooring location. However, it is doubtful that such a major burst of energy would be completely lost, since normal tidal flow has a significant westerly com- Ponent at this site, Sediments Data resulting from the heavy natal analysis of sediments from the Western Long Island Sound area are presented in Table I-4. Although tne Cable and Anchor Reef stations generally have higher concentrations than those from Western Long Island Sound, both sites are similar and significantly higher than all other areas sampled in this study. Since the background sediments at the Western Long Island Sound site are so high, it 1s doubtful that spoils would be easily de- tected at this location based on chemical data. Biochemical Studies Mussels from Latimer's Light were deployed at the proposed Western Long Island Sound disposal site at 41900'51.9" N, 73921'16.5" W, at the Cable and Anchor Reef site at 41900'27.6" N, 73926'10" W, and at a common reference station at 41023'24.8" N, 73023'52.3"W.

The baseline data and results from the cages are presented in Table I-5 and Figure I-10. At both disposal sites the behavior of the mussels was similar with Cd and Cu showing significant increases in con- centration while Zn approached but did not exceed the confidence limits. Following sampling in July, the Western Long Island Sound cage was destroyed by a dragger and problems were experienced retrieving the cage at Cable and Anchor Reef. It appears that the large amount of fishinu activity in this area will severely restrict the use of instrumentation in this area. Benthic Macrofauna The numeric density data of the benthic population in Western Long Island Sound are presented in Tables I-6, I-7, and I-8. The most sianificant factor noticed in this area is the comparatively low number of individuals sampled relative to other sites in this study. Values for Diversity and Equitability are similar for all three stations. Fisheries The major objective of fisheries studies in this area is to map fisheries jin the area east of Cable and Anchor Reef for a distance of approximately 7 miles. This information will be used along with bottom current measurements to choose a nossible disposal site. Information on recovery times and fisheries potential of discontinued disposal areas is also being collected. Choice of a disposal area in Western Long Island Sound is difficult because almost all of the area deeper than 20 meters is used by commercial lobstermen, Fishermen from different ports are limited to informal "territories" and so are Concerned about any reduction in their fishable area.

In September, 1978 the Connecticut Commercial Fisherman's Association was formed. It is hoped that the existance of this group will help in assembling information on the fisheries of the Western Sound. Fisheries. Lobstering is the dominant fishery in the area under consideration. Table H-9 shows that in 1977 41.8% of the lobsters caught in the Sound came from a relatively small area of western Connecticut (Fig. I-11). The adjacent NY area yielded only 3.6% of the catch, Although there are large lobster landings at Northport N.Y., most of this catch is also from Connecticut waters. The following annual pattern of fishing was described by Norwalk lobstermen: In March, fishing begins in the area between the 20 meter line and Cable and Anchor Reef. During late spring and early summer the gear is spread to the limit of Norwalk grounds east and west, between 2 meters and the N.Y. line. Pots are relatively heavy at the Eatons Neck dump site, Cable and Anchor Reef, Budd Reef, and along the 20 meter line. Gear may be placed in the deep channel east of the dump site in August, N.Y. fishermen may fish this channel from spring on, however. Cobb et al (1978) mapped lobstering grounds near the Eatons Neck dump site from observations made from November to June, 1974-75, Heavy pot densities were jound in the disposal graund in the summer. In the winter there were fewer pots, but these were found east of Cable and Anchor Reef, Travel samples taken by Cobb et al showed a similar movement in lobster densities in the valley east of the dump site which were seen in August, 1978. This map can be interpreted as showing the pattern of the New York-based fishery and the absence of near shore populations off New York in the winter. Penfield Reef dumping ground in the northeast corner of the map, has been a prime lobstering ground since its use was discontinued. A fisherman who fishes the area extensively reportec that he lost geay during the last disposal project there and that catches were low in the area until the year following its use. Details of lobstering effort have not yet been obtained for areas east of the area fished by Norwalk vessels. Concentration of gear on the edges of the central valley of the Sound has been reported. There may be advantages to a disposal site in areas "B" or "C" (Fig. I-11). The very productive grounds at the Eatons Neck dump site and the deep channel are avoided and the qreater area fished would allow adjustments to be made away from the site when active. The Current measurements and background measurements of metals "in" blue mussels being made in area "A" by DAMOS should be applicable to the general area. Finfish. Cobb et al (1978) also collected bottom fish at three stations monthly from November to June. They found 37 species, but 3 species dominated the catches. Windowpane flounder and winter flounder were found throughout the year, but were most abundant in April and January respectively. Red hake were abundant in June especially east of the disposal site. Commercial dragging is limited by the density of lobster pots in this area. There is a tow path from the Eatons Neck dump site 5 miles west to Buoy "32". Nragging is done in New York water south of 419 latitude and east of a line about 7 miles east of Cable and Anchor Reef. The fall scup fishery is the most intense. There may be fish on or off the bot:om depending on the leve! of the fish. Bottom fishing may also catch lobsters. Oys‘ers. The areas being studied lie seaward of hard bottomed areas used for oys er mariculture. Leases as deep as 40-50 feet are active (H. Bloom, Norwalk). Oyster set was very success ful throughout Long Island Sound in 1978, Ocean Quahog. The ocean quahog (Arctica Islandica) can be found in this area but there is no chance that it will be of commercial value in the study site due to the depth and nearly rocky bottoms. Much more favorable grounds are found off Massachusetts and Rhode Island (20-40 meters deep). These areas can easily saturate the market and the fishery has been barely economically viable in the last year. we
