The Moratuwa University’sTown Planning Studies section prepared the Hamilton Canal development plan which was implemented by the Economic Development Ministry. Under the plan’s First Stage a distance of eight kilometres from Negombo Lagoon up to Dandugum Oya river delta was developed. Under the second stage a distance of 11km is scheduled to be developed. A part of this - an extent of 3km from Hekiththa on the Kelani River in the Wattala Pradeshiya Sabha area to Elakanda has already been done.
Hamilton Canal project was launched with the objective of developing the NegomboTourism Zone. In connection with this steps have been taken to protect the rich biodiversity of the area thus protecting different species of fish, flora and fauna in and around the canal.
