FINAL Phase IB Underwater Archaeological Resources Report for Onondaga Lake Superfund Site A45 showed the site to be constructed of bags of concrete. Each concrete block was pillow shaped with two indentations from band that went around the bags. A74 A75 A55 A38 The breakwater was clearly built by throwing bags of concrete into the water. A53 was found during the survey. The remains were consistent with what was shown during ROV/sonar work and what was stated in the report. Numerous pieces of A53 were located around the wreck, particularly to the southeast. Disarticulated pieces included several frame sections, which were of cocked hat construction like the wreck itself. Each disarticulated piece was examined in detail to make sure it was not a larger section or a new wreck. 1211 AK swaps out tanks so that this area can be completed. 1217 AK back into the water. AK finishes the southeastern portion of the SMHD. 1300 AK out of the water. 1310 Depart and go back to area of A74 & A75 to record locations. Three points taken for A75. 1320 Depart A74 & A75 area. 1335 CS into the water for the shallow water survey of the area immediately north of A4-1 & A4-2. CS relocates A55 and A38. No other finds in this area. CS surveys from A4-1 to A55. 1515 CS out of the water. End of dive ops for today. 1525 Pull dive flags from survey area. 213
FINAL Phase IB Underwater Archaeological Resources Report for Onondaga Lake Superfund Site A17 1535 Arrive at A17 for inspection to determine documentation approach. Inspection shows the site to be two barges resting side by side. The inshore barge is about 50% buried. The approach will be to document the inside barge with chest waders and the outside one on scuba. 1550 Arrive at marina. 1600 AK departs to go out to buy chest waders. 1640 AK returns to marina with waders. 1650 Depart marina. 1705 Arrive hotel. End of day. June 27, 2011 0700 Arrive marina. ST, AK & CS. Already at marina, SD & CW of CRE and KM & Pete Petrone of Parsons. Load gear. The plan for today is to document the barges at A17, followed by more shallow water survey in the afternoon. 0745 Safety briefing. 0820 Depart marina for A17. A17 0830 Arrive A17. Proceed to document A17-2 (inshore barge) and A17-1 (outer barge). The barges are identical spud barges. The ends closest to the spud holders are vertical with vertical planking. The sides are vertical sides, built plank-on-frame. Approximately half of A17-2 is buried below the shore. Much of the machinery is not visible and/or gone, as opposed to A17-1, where the flywheel and other machinery is evident. The non-spud holder end of the barge is raked with transverse planking. Phragmites cover about ½ of A17-2. A17-1 was not documented in as much detail as A17-2 because it will not be impacted by the proposed shoreline improvements. Much of the interior structure of A17-1 is clearly visible, all the way down to the stringers and floors. The barges are both very shallow with a depth of +/- 3’. The hull structures consisted of planking, floors, and stringers. Those three, all connected, made up the entire depth of hull. The non-spud end of A17-1 had a mound of concrete immediately adjacent to it. Inspection of the concrete suggested that it was formed by pouring it into 214
