This is a cluster of four small reservoirs found in the southern section of the Kam Shan Country Park north of the Kowloon Peninsula. Collectively they have a capacity of 2.9 million cubic metres of fresh water. You can visit the reservoirs and their respective dam structures while hiking and sightseeing in the country park.
Historically, the Kowloon Reservoir was constructed in 1910, making it the fourth man made lake in Hong Kong and the first in the New Territories. The Shek Lei Pui Reservoir was completed in 1925, followed by the Kowloon Reception Reservoir (1926) and Kowloon Byewash Reservoir (1931).
Interestingly, there are 5 historic structures at the Kowloon Reservoir that are Declared Monument buildings in Hong Kong. These include the Main Dam, Main Dam Valve House, Spillway Dam, Spillway Dam Recorder House and the Recorder House all of which were completed in 1910 and designated as declared monuments in Hong Kong in 2009.
It is easy to visit the Kowloon Reservoir Group. The main Kowloon Reservoir is at the start of the MacLehose Trail Section #6 and entry into the Kam Shan Country Park just north of the Tai Po Road. You will see it and the dam structures immediately upon entering the park.
There is a short Kam Shan Tree Walk, an 800 metre hike that starts just north of the Main Dam on the Kowloon Reservoir. You can take this through the forested area around the Byewash Reservoir to the dam area of the Reception Reservoir. You can take an informal shoreline hike around the Reception Reservoir or continue on the Tree Walk which will later cross the Byewash Dam and back to Tai Po Road. There are other splinter trails, from Golden Hill Road north of the main Kowloon Reservoir from which you can use to make way over to Shek Lei Pui Reservoir as well.
