Water storage in reservoirs increased by nearly 15% after rainstorm, 6 reservoirs including Tai Tam Tuk are full for viewing flood discharge or have to wait longer

Hong Kong experienced several heavy rains last week, and the Hong Kong Observatory issued a red rainstorm warning signal at one point.

Despite the inconvenience caused by the torrential rain, the water storage in Hong Kong's reservoirs has benefited from this, which has increased by nearly 15% compared with last week, returning to the level of the same period last year.

On May 16, the water storage in the reservoirs surged by 45.98 million cubic meters compared to last week, which is equivalent to an increase of nearly 3.5 water volumes in the Shing Mun reservoirs.

Six reservoirs in Hong Kong were even hit by heavy rain, with the latest water storage reaching 100%, including Tai Tam Tuk Reservoir, Aberdeen Upper Reservoir and Kowloon Receiving Reservoir; In the pond, the water storage volume also rose to 24.8% from 3% at the beginning of the month.

Although the water storage capacity of many ponds reaches 100%, it may not be possible to see a spectacular flood discharge scene for the time being.

It is understood that although the water storage capacity of Tai Tam Tuk Reservoir reaches 100%, no overflow has been recorded recently.

The rainfall in Hong Kong in April was the lowest on record. The Observatory Headquarters recorded only 3.5 mm of rainfall throughout the month, which was only about 2% of the normal value.

The dry April also made the ponds "dry ponds". The water storage in the ponds on May 1 was 54.24%, compared with 54.43% on May 9 last week, both more than 8 percentage points lower than the 62.92% in the same period last year.

Among them, the water storage capacity of the Lower Shing Mun Reservoir is only 3.07%, while the water storage capacity of the Kowloon Sub-Reservoir and Shek Pik Reservoir is 30.25% and 49.25% respectively.

Last week, Hong Kong recorded consecutive heavy rains. The Observatory issued an amber rainstorm warning signal five times in two days, and the rainfall reached black rain in many areas.

The Water Supplies Department announced that the water storage in the ponds rose to 62.28% on May 16, a sharp increase of 14.4% from last week, which was similar to the level of the same period last year, but was still lower than the warning line of 70%.

Shing Mun Reservoir and Tai Lam Chung Reservoir, known as the "Hong Kong version of Qiandao Lake", also recorded 90.04% and 91.82% of their water storage, up 17.2 and 28.4 percentage points from May 1.

As for whether there will be a spectacular flood discharge scene in the reservoir, "Hong Kong 01" has inquired with the Water Supplies Department and has yet to respond.

However, it is understood that the Shing Mun Reservoir and Tai Tam Tuk Reservoir, which are popular places for viewing flood discharge, have not recorded overflows recently.
