Urrunaga Reservoir
(Spain)
Description
It is the second biggest reservoir operated by Consorcio de Aguas Bilbao Vizcaya, which supplies more than one million inhabitants, 91.26% of which are from Biscay, which is 48.20% of the total Basque Country population. This reservoir has a maximum capacity of 72 hm3, a surface of 785 ha and a maximum depth of 24.5 m.
Current situation
During the 2017-2021 period, the reservoir presented a maximum of 5.53 μg/L of Chl a, a minimum of 0.57 micrograms, with an average value of 2.06 μg/L with a bloom caused by Microcystis and Pseudonabaena. This recreational lake is expected to obtain larger Chl a concentration values, especially during summer, when this reservoir is most necessary for supply, since under the new climate scenario, precipitation patterns make the summer period increasingly dry in the region.
Actions to be carried out within the LIFE CYANOBLOOM project
In this demo site, intensive in-situ sampling campaigns will be carried out between the months of May and October, 2024. In addition to specific campaigns outside that time period with the aim of monitoring the evolution of the cyanobacteria group within the reservoir. Also, the installation of a WISPstation, which will collect hyperspectral field data coinciding with the in-situ monitoring will be done.
Expected results
With the tool developed in cyanobloom, it is expected to achieve more efficient and safer management of the resource under the threat of toxic cyanobacteria blooms.
