The tropical cyclones "Lion Rock" and "Compasses" struck Hong Kong within 4 days. In addition to the No. 8 typhoon signal, the Observatory also issued a black rainstorm warning signal on the 8th of this month. Multiple days of torrential rains and flooding occurred in many places


The tropical cyclones "Lion Rock" and "Compasses" struck Hong Kong within 4 days. In addition to the No. 8 typhoon signal, the Observatory also issued a black rainstorm warning signal on the 8th of this month.

After several consecutive days of violent storms, flooding occurred in many places and turned into a country. The total water storage capacity of the reservoirs in Hong Kong also increased from 67.96% to 76.89%.


A total of 10 reservoirs in many districts in Hong Kong are full. In addition to the Tai Tam Tuk Reservoir on Hong Kong Island, which cannot carry more water and needs to "release water" to discharge the flood, the Shing Mun Reservoir is also full of water. The "flood funnel" is a spectacular picture of drainage. , And attracted many photography fans to shoot.

Water storage in reservoirs soared by 9%

According to data from the Water Supplies Department, the total storage volume of the ponds in the Port of Japan on October 4 was 396.5 million cubic meters, accounting for 67.67% of the capacity.

However, after the tropical cyclone "Lion Rock" struck, the record on the 11th increased significantly to 75.32%; the "compass" that struck afterwards was less rainy, and the reservoir water storage volume recorded on the 18th only rose to 76.96% , The total water storage is 451 million cubic meters, which is still 5 percentage points less than the same period last year.

Therefore, after the two tropical cyclones, the water storage in Hong Kong's reservoirs increased by 9.29%.

Among the 17 reservoirs in Hong Kong, the capacity of 10 of them still reached 100% on October 16, including Aberdeen Lower Reservoir, Aberdeen Sheung Reservoir, Tai Tam Secondary Reservoir, Tai Tam Tuk Reservoir, and Tai Tam Sheung Reservoir, Shek Pik Reservoir, Kowloon Secondary Reservoir, Shilibei Reservoir, Kowloon Receiving Reservoir, Shing Mun Reservoir.

Tai Tam Tuk Reservoir and Shing Mun Reservoir need to "drain flood"

The reservoir with the highest increase was not full. The water storage in Tai Lam Chung Reservoir increased from 48.14% to 95.88%, an increase of 47.74%.

The Shilibei Reservoir was followed by a sharp increase in water storage from 58.56% to full, an increase of 41.44%.

The reservoir with the smallest increase was the Kowloon Reservoir, with water storage slightly increasing from 82.07% to 84.60%, an increase of 2.53 percentage points.

Followed by the Aberdeen Lower Reservoir, which rose from a nearly full 96.71% to 100%, an increase of 3.29%.

When the water storage in the reservoir needs to be drained, the "black rain" was full when the Tai Tam Tuk Reservoir was in Lion Rock. The weather improved on the 11th, and there was still a waterfall in the dam. After the compasses passed, the city gate water The "flood-draining funnel" of the pond has a drainage wonder, which is the target of many photography "seasonal limited".

Water storage is still about 5% less than the same period last year, unable to "run back to the market"

The rainfall in Hong Kong this summer was relatively small. Even after two tropical cyclones, the water storage in the reservoirs still failed to "recover the market."

According to data, the total water storage capacity of the reservoir in the same period last year was 480 million cubic meters, accounting for 81.95% of the capacity, which was about 29 million cubic meters more than last week.

He Jianzong, the former chairman of the Water Quality Advisory Committee, has described in past interviews that the "warning level" of water storage in reservoirs is 70%, that is, it has returned to the target of safety.
