The Kowloon Byewash Reservoir was completed in 1931. Its completion was reported in the Public Works Department's Annual Report for that year:

141.    Water from the new Byewash Dam became available on 16th January, 1931. This dam which forms the connecting link between the Kowloon Reservoir and the Shing Mun Supply has a capacity of 185.50 million gallons and provides a much needed addition to the mainland storage.

A 'clearwater reservoir' is marked in this location (opposite the Pumping Station) on the 1896 and 1920 Kowloon maps.

The 1895 Public Works Report states: 

This tunnel was part of the first section (phase) of the Shing Mun Valley Scheme. It is marked (I) on the map below.

The completion of the project is mentioned in item 47.iv of the PWD's Annual report for 1897. I've highlighted the comment about the "roof formed of brick arching", which suggests it is similar in style to the service reservoir at Bishop's Hill, unless it has been rebuilt at some point.

One of two reservoirs that appear on the 1889 map. They are labeled Sugar Works Reservoirs. Possibly built at the same time as the Sugar Refinery.

Was demolished about 1970 and used for housing estates and Taikoo Primary School.

The very first dam in Hong Kong was built at Pokfulam. A masonry dam was built across "Pokfoolum" valley to collect rainwater. For the transport of water to Victoria, a ten-inch cast-iron pipe was laid from the reservoir along todays Pok Fu Lam Road to finally Bonham Road. The work was finished in 1863, the reservoir had a capacity of 2 million gallons (9100 m³). The dam was near the (todays) Jockey Club  PHAB Centre, the reservoir stretched out to near Douglas Castle.

In 1978, the old dam was demolished in construction works.
