Jordan Valley Reservoir, reservoir in Hong Kong

Jordan Valley Reservoir was a saltwater storage reservoir in Kwun Tong District, completed in 1960 with a main dam about 29 metres high and 85 to 90 metres wide. It held roughly 236,400 cubic metres for flushing supply. It was filled in during the early 1980s; the site is now part of the former Jordan Valley landfill, with Jordan Valley Park opened in September 2010 to its northwest.

Planned in 1958 and completed in 1960, the reservoir stored about 236,400 cubic metres of seawater for flushing in Kwun Tong and Shun Lee, with a main dam roughly 29 m high and 85–90 m wide. It was abandoned in the early 1980s; after complaints about mosquitoes it was found still waterlogged and only fully filled in 1985, becoming part of the Jordan Valley landfill.

The name Jordan Valley comes from the colonial-era "River Jordan" stream drawn on M.S. Wong's 1958 dam plan (W.3156), not from a doctor. The reservoir stored seawater for flushing in Kwun Tong and Sau Mau Ping, and supplied the Jordan Valley Estate and the Amoy Food factory below. The dam survives, and elderly morning exercisers still climb onto it from paths near Shun Lee and Amoy Gardens.

The reservoir site lies within a landfill under restoration and is closed to the public; the northwestern part became Jordan Valley Park, opened in September 2010. The main dam can still be reached on foot from the Amoy Gardens area, following the Jordan Valley nullah to the foot of the hill and up past the Shum Wan Shan fresh water pumping station. Beware of stray dogs on the path. The dam is used each morning by elderly residents doing exercises.

The reservoir's main dam, about 29 metres high and 85 to 90 metres wide, still stands and can be reached by a path from the Shun Lee and Amoy Gardens area. Morning walkers climb onto it for exercise. The reservoir site itself lies within a landfill under restoration and is closed to the public.
