Oliana Reservoir

Nature · Oliana, Alt Urgell, Lleida

The Oliana reservoir, a large dam on the river Segre at the foot of Oliana castle, came into operation in 1958. At its tail, where the dammed waters form a large meander and receive those of the río de Perles, lies a wetland of about 49 hectares with well-preserved white willow groves and isolated specimens of poplar and ash. There was historically established the first breeding colony of the yellow-legged gull in the western comarques, and downstream of the dam stable otter populations are maintained. The reservoir suffers, however, from sudden changes in water level and gravel extraction that have degraded part of the riverside woodland at the tail.
