The heavy rains caused by DANA caused dam water levels to rise in Aragon. The marshes exceed, on average, 70% of their capacity, with 226 cubic hectometers more accumulated compared to last week. There are some, like Medium, which are close to 100%. Concretely, it is 98%, with 425.7 cubic hectometers out of a total of 434.5.
The latest report from the Hydrographic Confederation (CHE) reveals the exceptional situation experienced by most reservoirs, close to their historical maximums, due to storms. The 5,618 cubic hectometers seized exceed the 2023 average by more than 33 points and in addition to 24 the reference of the last five years. These are in fact the best data for the current hydrological year.
After the irrigation campaign, the main reservoirs of the Community should be half empty. The current picture, however, is very different. a far cry from years of restrictions due to lack of precipitation.
The Barasona reservoir is at 93.4% and Yesa exceeds 80%, while La Tranquera reaches 79%. The increase on the right bank, affected for years by drought, is particularly significant. If a week ago the reservoirs were at 39% with 267 cubic hectometers, this week they reached 51%, a difference of 12 points which translates into 81 additional cubic hectometers.
The differences are more than obvious compared to the 35% a year ago, where they were at a minimum with only 240 cubic hectometers, or 47%, which is the average for the last five years.
For days, the CHE has been closely monitoring the Guadalope and Matarraña due to the risk of flash floods and the effects on municipalities. The situation now seems much more under control. However, since Confederation, it has maintained until this morning the warning of heavy showers and persisting in Matarraña itself, where significant flooding cannot be excluded.
On the other hand, the reservoirs of the Huerva, Las Torcas and Mezalocha river basin, which last week reached 100% of their capacity to be able to overcome the flood, are currently at 84% and 86% respectively, returning to a “normal” situation.
