The Espolla swamp is a reservoir that belongs to the Ribera de Sant Genís, created by a dam built in the 1970s. The swamp collects the surface water from the natural upstream drainage, which comes from the surface runoff from part of the southern slope of the Massís de l'Albera and the underground water that emerges at the level of the reservoir. In 2021, it supplied a total of 21,973 m³ (45.6% of the flow captured), while in 2022, the reservoir supplied a total of 15,184 m³ (35.5%). In both cases the volume is much lower than the maximum authorized in the concession approved by the defunct Comisaria de Aguas del Pirineo Oriental in 1972 (189,216 m³/year). The waters of the swamp are sent to the Espolla reservoir, with a capacity of 300 m³, where they first pass through a sand filter that has been put out of service. It is in the tank where this water is mixed with the bulk purchase from the Commonwealth. https://commons.wikimedia.org/wiki/File:PRESA_DE_ESPOLLA_2.jpg Presa d'Espolla is in Catalonia, East of Spain. Presa d'Espolla is located near the archaeological site Dolmen de Les Morelles and Dolmen dels Arreganyats.

The Portbou marsh is a reservoir that belongs to the Portbou stream, created by a dam located in the municipality of Portbou in the region of Alt Empordà. It was built between 1973 and 1975 in order to solve the drinking water supply of Portbou. It is one of the smallest in Catalonia. The height of the dam is 27.5 m and its capacity is 1 hm³. Its surroundings are an ideal place that invites you to go on a short excursion and be able to enjoy its surroundings, all surrounded by a lot of pine forest.

simple good food with friendly service and a wonderfully pleasant atmosphere. Perfect after a long hike or to pop in for a swim. You only pay entrance fee when you enter the water

Beautiful views of the Delfià pools or also known as Faiet pools. An amazing roadside find.

There is a nice rest area at the dam wall

A very nice corner, the small detour from the GR 92 is worthwhile. The free-range cow herd with calves and bulls on the wayside behaves peacefully.

The route is suitable for birdwatchers. You pass the bird protection reservoir Aiguamolls. In the middle of the track a very nice bird watching station. The second part of the track is exceptionally beautiful. In summer (Weigegrund) the dog has to be leashed there.
