Gwadar Bay is located in the Gulf of Oman on the maritime border of Pakistan and Iran. The name is from Persian, Khalij-e Gavader or 'Gulf of Gwadar' on Arabian Sea. It is an inlet of the Arabian Sea indenting the sandy Makran coast at the Iran–Pakistan border. It is about 20 miles (32 km) long and 10 miles (16 km) wide. The Dashtiari River flows into it from the northwest, and the Dasht River from the northeast. The town of Gwadar, which has no sewerage system nor protection from the Bay, lies on the Arabian Sea coast about 30 miles (48 km) to the east of Gwadar Bay.
