The latest surface water monitoring data: 55% of the country's dam reservoir capacity is empty

The latest data of the country's surface water monitoring show that despite the relative improvement in the volume of dams compared to last year, 55% of the country's storage capacity is empty.

According to Ambassador Arjan's report, until Mehr 19, since the beginning of the water year 1405-1406, the total water input to the country's dam reservoirs was 0.82 billion cubic meters; A figure that shows a 62% increase compared to the same period of the last water year, according to the official statistics of monitoring the state of dams, but it is still one percent less than the 10-year average. The volume of water in the dams has also reached 23 billion 310 million cubic meters, which is 30% more compared to last year and 4% more than the long-term average.

Ilna wrote: However, 55% of the country's dam reservoir capacity is still empty, and especially in the Tehran and Alborz aquifers, the situation of Lar, Taleghan, Letian and Mamlo dams is negative and worrisome compared to the 10-year average.

Based on this, the Amirkabir dam has 21% more storage than the 10-year average with 72% filling. Taleghan dam is 33% negative compared to the 10-year average. Letian and Mamlu are also negative 38% and 74% respectively compared to the 10-year average.

Rainfall monitoring also shows that the total height of atmospheric precipitation in the country was 4.2 mm, which is more than the same period last year, but still has a significant distance from the long-term average, and six provinces, including Fars, Sistan and Baluchistan, Kohgiluyeh and Boyar Ahmad, Bushehr, Yazd, South Khorasan, have not received any rain and are living in zero conditions. A pattern that will intensify the double pressure on the underground resources of these provinces in the coming months.

An important issue in the current water year is predicting the occurrence of El Nino, which of course, according to the Water Research Institute, the El Nino that the country is facing this year, can result in both rainfall and a significant increase in temperature.

The analysis of forecasting models shows that there is a possibility of an increase in rainfall in some regions of the country, especially in the west and southwest, and the estimates indicate the possibility of an increase of 30 to 70 mm of rainfall in some regions with a probability of about 70% in the west of the country. Rainfall forecasts are mentioned.

In a situation where the country has experienced five consecutive years of drought and the pressure on underground water resources has increased, it is necessary to plan the supply of drinking water, industry and agriculture in the coming months.

Anyway; Although the volume is 30% more than last year and 4% more than the long-term average, it may seem promising at first glance, but the fact is that 55% of the country's reservoir capacity is empty. In other words, more than half of the country's storage capacity is left without water and the drought has not yet ended.
