Figure 43. View of 1,814-kg (2-ton) dolosse along trunk of Cleveland 

 Harbor east breakwater 



with detailed, rectified aerial photography, in general, revealed that most 

 of the armor units were in the same position as in 1993. Even fragments 

 of broken dolosse were in the same positions based on the aerial photo- 

 graphs. Apparent armor unit movement was observed at only one location 

 along the structure. At sta 262+55 one dolos had moved downslope 

 slightly and an adjacent dolos had flipped upslope. It was also noted that 

 some new 3,628-kg (4-ton) dolosse had been placed between sta 253+50 

 and 254+00 since 1993. The structure is in fair to good condition and ap- 

 pears to be functioning well. 



Cattaraugus Creek Harbor Breakwater, New 

 York 



Cattaraugus Creek Harbor, New York, is located on Lake Erie approxi- 

 mately 38 km (24 miles) southwest of Buffalo, NY, and 87 km (54 miles) 

 northeast of Erie, PA. The project consists of two breakwaters in Lake 

 Erie at the mouth of the creek, a north breakwater 183 m long (600 ft 

 long), and a south breakwater 564 m long (1,850 ft long); an entrance 

 channel with el -1.7 m (-5.5 ft) Iwd; and an interior channel extending up- 

 stream about 1,067 m (3,500 ft) with el -1.1 m (-3.5 ft) lwd. The break- 

 waters are of rubble-mound construction, and the south structure has a 

 massive concrete cap, which provides a walkway for fishermen. Armor 

 stone for the south breakwater ranges from 1,814 kg to 4,536 kg (2 to 

 5 tons) at the shore end to 5,443 kg to 11,793 kg (6 to 13 tons) at the
