The Department of Infrastructure has had to bring in specialist contractors in order to make progress with dredging Douglas Harbour.
Infrastructure Minister Tim Crookall was asked in the House of Keys this week for an update on the works by Arbory, Castletown and Malew MHK Jason Moorhouse.
Mr Crookall said a raised area in the central harbour has been causing problems for navigation with boats.
He explained why the problem had proved hard to solve:
Rapists's appeal against sentence thrown out
Last chance to become next TT's charity partner
No gas price hike after regulator review
Cafe hits back after staff abused
Online appointments being considered by sexual health clinic
Treasury can’t say how much is made from medicinal cannabis
Road closures planned for tin baths this weekend
