Question: was the developing and dredging of dubai creek started in 1920s

Answer: No, Fishing, also an important industry at the time, was also based along the creek, whose warm and shallow waters supported a wide variety of marine life. Dhows used for purposes of fishing were also built on the foreshore of the creek. The importance of the creek as a site of commercial activity was a justification to introduce improvements to allow larger vessels to transit, as well as to facilitate loading and unloading activities. This led, in 1955, to a plan to develop the creek, which involved dredging shallow areas, building of breakwaters, and developing its beach to become a quay suitable for loading and unloading of cargo. The creek was first dredged in 1961 to permit 7-foot (2.1 m) draft vessels to cross through the creek at all times. The creek was dredged again in the 1960s and 1970s so that it could offer anchorage for local and coastal shipping of up to about 500 tons. The dredging opened up the creek to much more continuous traffic of merchandise, including the development of re-export, and gave Dubai an advantage over Sharjah, the other dominant trading centre in the region at the time. Al Maktoum Bridge, the first bridge connecting Bur Dubai and Deira was constructed in 1963. Although the importance of the creek as a port has diminished with the development of the Jebel Ali Port, smaller facilities, such as Port Saeed, continue to exist along the creek, providing porting to traders from the region and the subcontinent.
