The world's first dock at Lothal (2400 BCE) was located away from the main current to avoid deposition of silt.[16] Modern oceanographers have observed that the Harappans must have possessed great knowledge relating to tides in order to build such a dock on the ever-shifting course of the Sabarmati, as well as exemplary hydrography and maritime engineering.[16] This was the earliest known dock found in the world, equipped to berth and service ships.[16] It is speculated that Lothal engineers studied tidal movements, and their effects on brick-built structures, since the walls are of kiln-burnt bricks.[17] This knowledge also enabled them to select Lothal's location in the first place, as the Gulf of Khambhat has the highest tidal amplitude and ships can be sluiced through flow tides in the river estuary.[17] The engineers built a trapezoidal structure, with north-south arms of average 21.8 metres (71.5 ft), and east-west arms of 37 metres (121 ft).[17]

Lothal is one of the most prominent cities of the ancient Indus valley civilization. Located in the modern state of Gujarāt and dating from 2400 BCE, it is one of India's most important archaeological site that dates from that era. Discovered in 1954, Lothal was excavated from February 13, 1955 to May 19, 1960 by the Archaeological Survey of India (ASI). Lothal's dock—the world's earliest—connected the city to an ancient course of the Sabarmati river on the trade route between Harappan cities in Sindh and the peninsula of Saurashtra when the surrounding Kutch desert of today was a part of the Arabian Sea. It was a vital and thriving trade centre in ancient times, with its trade of beads, gems and valuable ornaments reaching the far corners of West Asia and Africa. Lothal's people were responsible for the earliest-known portrayals of realism in art and sculpture, telling some of the most well-known fables of today. Its scientists used a shell compass and divided the horizon and sky into 8–12 whole parts, possibly pioneering the study of stars and advanced navigation—2000 years before the Greeks. The techniques and tools they pioneered for bead-making and in metallurgy have stood the test of time for over 4000 years.

Nice find, i did a lil Googe'ing and found some great sources of Info on that. Have you ever heard of Tianhuanaco in Bolivia ? It is also a port, which used to be located on the edge of a lake. The lake has now receded greatly, the lake is now 15+ miles away and they think it would of took 12,000+ years for it to receded so far, any one heard that ? I only found it after looking at this one...

A port is a facility for receiving ships and transferring cargo. They are usually found at the edge of an ocean, sea, river, or lake.

A dock (from Dutch 'dok') is a man-made feature involved in the handling of boats or ships. However the exact meaning varies between different variants of the English language.

harbor or harbour (see spelling differences), or haven, is a place where ships may shelter from the weather or are stored. Harbors can be man-made or natural. A man-made harbor will have sea walls or breakwaters and may require dredging. A natural harbor is surrounded on most sides by land. Harbors and ports are often confused. A port is a man-made coastal or riverine facility where boats and ships can load and unload. It may consist of quays, wharfs, jetties, piers and slipways with cranes or ramps. A port may have magazine buildings or warehouses for storage of goods and a transport system, such railway, road transport or pipeline transport facilities for relaying goods inland.
