he Bales SwampLike the rest of the Catalan marshes, it continues to be in free fall in terms of reserves, currently standing at just over 20% of its capacity. despite this, It is still some point above the historical minimum.
he All internal sink tanks From Catalonia It has been many weeks since they reached an all-time low for such a ratio. Specifically, at the beginning of November last year, when they withdrew from 18.98%, below the level of severe drought in 1989.
currently Inland basin swamps: 15.62%with a total tank water volume of 108.5 µm3. Never before have they stored so little water.
La Bailles, a swamp that shows the pulse of drought in the Eastern Pyrenees
The Bayless Swamp is located in the Berguida area and is the only reservoir in the Llobregat River Basin. the The variation in size of this swamp depends on the amount of rain collected at the headland. The water receiving basin, which is relatively small, extends from the foothills of the Cadi, Piedrafurca, Rasos de Peguera and Serra Dencija (to the west) to the Catlaras massif (to the east), passing through the Moixeiro mountain range and the Encija River. Tossa-Puiglansada massif (in the north).
the Pyles is the only marsh in the Terre Llobregat system that cannot be organized with any other marsh, as it cannot transfer water to any other reservoir. This is not the case with the Sau-Susqueda system, or the Llosa del Cavall – Sant Ponç system. The clearest example is Sao, currently more empty than ever Because of the obvious reason for the severe drought, but also because of the transportation to Susqueda to ensure the good quality of the reservoir water at this second.
Therefore, It is a good thermometer for the development of drought in a particular area of Catalan territoryAnd the headwaters of the Llobregat and Bastarini Rivers and the Saldes River. the Variations in its level are closely related to the development of precipitation In the Eastern Pyrenees.
The Bales Swamp has been many times emptier than it is now
Biles is currently in Capacity 20.7%. Although it is a really low level, it is worth remembering that This swamp has become more empty at other times. Among the historical lows it is worth noting:
- Absolute minimum 15.19% on April 3, 1987.
- Minimum drought for the years 2005-2008, 18.7% on October 12, 2005.
- 1989-1990 minimum drought, 19.69% on April 25, 1990.
- The minimum before the end of the drought of 2005-2008, 20.4% on April 6, 2008.
The precipitation that falls on the head is beyond doubt The most relevant item that represents the pulse of Bales Swamp levelBut he's not the only one. The level difference is also subject to Water needs at the historical moment. For example, today, although water needs are higher than at the end of the 1980s, at that time they did not have desalination plants or renewable water, so the dependence on swamps was clearly higher than on the stream.
Sao, it has never been as empty as it is now
The Sao Swamp is currently at 3.83% capacitycontains 6.32 HM3 of water, the lowest level since its construction in the early 1960s. On January 13 of this year, its capacity dropped to less than 5.77%, the lowest level recorded on April 20, 1990 (the lowest value since its construction).
The reason for the low level of this swamp, apart from the severe drought in the Eastern Pyrenees, is the water transfer that still occurs for the benefit of Susqueda.
