The reservoir was built as part of an infrastructure project to secure irrigation for the Alt Empordà region.
The dam is a gravity-arch structure reaching a height of approximately 63 meters.
The reservoir has a total capacity of roughly 62 cubic hectometers.
It is a key habitat for various bird species, making it a recognized area for birdwatching in northern Catalonia.
The water level often exposes older ruins or infrastructure during periods of severe drought.
Embassament de Darnius-Boadella is a large reservoir created by a dam on the Muga River in the Alt Empordà region of Catalonia. The reservoir covers approximately 630 hectares and serves as a major water supply and flood control structure for the surrounding agricultural plains. Its surroundings are characterized by Mediterranean forests of holm oak and cork oak. The site is a primary destination for freshwater recreational activities including swimming, kayaking, and paddleboarding. Angling is a popular pursuit, with the reservoir known for populations of black bass and pike. The terrain around the lake is rugged, featuring several marked trails suitable for hiking and mountain biking. The reservoir's water levels fluctuate significantly depending on seasonal rainfall and agricultural demand. The dam structure itself was completed in the late 1960s to regulate the erratic flow of the Muga River.
The elevated lookout points along the GIP-5041 road offer panoramic views of the water against the backdrop of the Pyrenees.
