The Kaveri River diverges at the Upper Anaicut, a dam at the island's westernmost point.
While the Kollidam continues flowing east past the island unimpeded, the Grand Anaicut dams the Kaveri at the island's eastern end, splitting the river into four streams.
One stream flows northeast for a short distance, joining the Kollidam and cutting off Srirangam Island on its eastern end.
Most of the island forms part of the Srirangam zone of the Tiruchirappalli Municipal Corporation and includes the suburbs of Srirangam, Thiruvanaikaval, Srinivasa Nagar and Gitapuram.
