Dwarka is the headquarters of the Okhamandal taluka in Jamnagar District
and is situated in the extreme west coast of the Saurashtra peninsula on the Arabian Sea. Similar discoveries of stone anchors from Indian Ocean coastlines suggest that Dwarka anchors may be related to Indo-Arab trade between 8th century and 15th century AD.
Referring to research by National Institute Of Oceanography in 2005, the anchors of Dwarka are not found to be associated with the Harappan or the Late Harappan Phase. The concentration of the stone blocks and structures are observed only at one location opposite to Gomati river mouth, and at no other locations in the area. The exact period of these submerged structures are still a matter of debate since surrounding archaeological site study indicates that the submerged structure may not be as old as suggested earlier.
Based on extensive, systematic underwater scanning of the area and specially absence of any pottery or other artefact even after airlift operations / underwater excavation at several places during last few years, present
exploration do not suggest that they belong to some habitation site, they rather appear to be the remains of a jetty.
