About the River Lagan and weir

Using the River Lagan

The department has responsibility for the Lagan Weir which has five flap gates which control the water levels upstream to Stranmillis Weir a distance of 4.8km. The gates can be operated to allow boats across the weir to the upper stretches of the river.

The river is primarily used by rowers from the private boats clubs. The Lagan Watersports Centre also runs sailing and canoeing on the river. A commercial river boat operates from the weir and provides tours upstream and downstream around the Titanic quarter.

You can find information about using the River Lagan including how to cross the Lagan weir, where to moor your vessel and where to launch from on the River Lagan page on the nidirect site. There is also a Guide to the Tidal Lagan which tries to answer many of the common questions about navigating the stretch of the River Lagan through the centre of Belfast.

River notices and Laganside events

You will find notices and events for the River Lagan and the Laganside area on the River notices and Laganside events page.

Speed boats, jet skis and water skiers are not allowed on the river except during an event which has been approved by the River Manager.

Biodiversity on the River Lagan

Part of our responsibility for the River Lagan is to continue the transformation of the river - this includes protecting and enhancing biodiversity. A Biodiversity Study was commissioned and a programme of work is now being delivered. Read more on the Biodiversity on the River Lagan page.
