A backwater is formed 4 to 6 miles NNE of Kottapatam by the confluence of the Mudigorda Yeru River and the Gundlakamma River. During fine weather, the latter river is available to small boats.
A beacon lies about 0.5 mile within the Mudigorda Yeru River.
From the mouth of the Gundlakamma River, the bay shore curves NE for about 35 miles to the entrance of a creek leading to the town of Nizampatam. Dindi House, a large building with a big high tree close E of it, lies on the N entrance point of the creek.
A light is shown from a white tower, 30m high, with red bands.
Between Dindi House and False Divi Point, almost 13 miles to the SE, the coast remains low and sandy.
A beacon lies on the NW entrance point of a boat creek about 5 miles E of Dindi House.
In Nizampatam Bay, weak tidal currents are experienced inshore only at spring tides.
