Dongri Point, the S entrance point of Bassein Creek, is a bluff point as seen from seaward. It rises to an elevation of 94m about 0.5 mile S of the point, and then slopes gradually to level country about 2 miles farther S.

A light is shown from about mid-September to mid-June.

Poshpir, a rocky islet 13m high, lies about 3 miles NW of Dongri Point.

Drying rocks extend about 2 miles WNW of the same point.
When there is no wind the sea does not break on the drying rocks and the sand banks in the entrance to Bassein Creek, and there are no indications of their existence.

Depths of less than 5m extend about 3.5 miles W of the entrance to Bassein Creek.

Tides—Currents:

Currents in Bassein Creek attain a velocity of 3 knots at springs, but about 5 miles above the entrance they decreases to 1.5 and 2 knots. In the creek the tidal currents continue to set about 1 hour after the times of HW and LW. Slack water lasts for about 15 to 25 minutes.

Vasai lies about 0.5 mile inland on the N side of the creek. A fort, with the citadel near the middle, lies S of Bassein near the landing place.
