Multitemporal Satellite Analysis of Laguna Fea, Province of Neuquén

In March 2017, with the participation of professionals from national and provincial departments, a survey was carried out in a remote area with difficult access in the north of the province of Neuquén, adjacent to the province of Mendoza and the Republic of Chile, where the Fea lagoon is located. It...

It is placed in a glacial trough at a height of 2.300 m, in a volcanic and tectonically active area, in the upper basin of the Barrancas River, one of the main tributaries of the Colorado River. The natural overflow of the basin would affect the populations located downstream, and even with the possibility of endangering the stability of the Casa de Piedra reservoir, it has led to the carrying out of studies of various kinds, complementary to the periodic measurements of the lagoon water level. The decrease in the hydrometric levels of the lagoon led to the need to identify the degree of link that could exist between the above-mentioned reduction of the body of water and the development of natural springs in the southeast of the mountain range called Infiernillo, where greater availability humidity allows the proliferation of mallines. In order to establish the degree of link between the development of mallines and the runoff from the lagoon, the advantages offered by remote sensing were use through mapping, quantification and temporal evolution of the surface of the lagoon and the area of mallines, for the period 1975-2020. En el mes de marzo de 2017, con la participación de profesionales de reparticiones nacionales y provinciales, se llevó a cabo el reconocimiento de un área remota y de difícil acceso en el norte de la provincia de Neuquén, colindante con la provincia de Mendoza y la República de Chile, donde se localiza la laguna Fea. El cuerpo de agua se encuentra alojado en una artesa glacial a una altura de 2.300 m, en un área volcánica y tectónicamente activa, en las cabeceras del río Barrancas, uno de los principales afluentes del río Colorado. El desborde natural del cuenco afectaría a las poblaciones situadas aguas abajo, y con la posibilidad de poner en riesgo la estabilidad del Embalse Casa de Piedra, ha llevado a la realización de estudios de diversa índole, complementarios a las mediciones periódicas del nivel de la laguna. La disminución de los niveles hidrométricos de la laguna, llevó a la necesidad de identificar el grado de vinculación que pudiera existir entre la mencionada reducción del cuerpo de agua y el desarrollo de vertientes naturales en el sudeste del cordón montañoso denominado Infiernillo, donde una mayor disponibilidad de humedad posibilita la proliferación de mallines. Con el objeto de establecer el grado de vinculación entre el desarrollo de mallines con el escurrimiento de la laguna, se ha utilizado las ventajas que ofrece la percepción remota a través del mapeo, la cuantificación y evolución temporal de la superficie de la laguna y del área de mallines, para el período 1975-2020.
