The ornate wall constructed on the edge of a section of the lake's perimeter that runs from Ulpange (Queens' Bathing Pavilion) to Bisokotuwa (Water Spill area) of the Kandy Lake had been completed only partially  by the time the Kandyan Kingdom was taken over by the British . In 1817, it had been constructed up to present Queens Hotel main entrance according to the landscape painting of Lt.William Lyttleton. The decorative wall is often wrongly identified as 'Walakulu Bamma'(Cloud Drift Wall) but the correct name of it is ' Diyareli Bamma' (Water Swell Wall). Professor Anuradha Seneviratna (1938-2009), a prominent Sri Lankan researcher and expert on Kandyan history, archaeology, and architecture, quotes this in his much praised book titled "Kandy" ( Central Cultural Fund – 1983 ).
“The ornamental wall round the lake was designed to resemble a wave- swell and is therefore called Diyareli bemma as opposed to the Walakulu bemma or cloud-drift found in the Dalada Maligawa parapets.”
