It is located in a shallow depression with irregular and very unstable contours near the sea, whose natural barrier separating it from the marine environment is formed by a line of coastal dunes. It is connected to the sea by a channel of variable width and positioning, locally known as "open". Sometimes this transition point closes, requiring interventions to keep the bar open. It is a lagoon system of enormous ecological importance. The Óbidos Lagoon is the largest coastal lagoon system on the Portuguese coast. It has a total area of approximately 6.9 km2 and an average depth of two metres, with elevations ranging from half a metre to five metres. It extends upstream essentially by two channels, to the west by the Braço do Bom Sucesso, and to the east by the Braço da Barrosa. (Source: Wikipedia)

The Arnóia River rises in the Serra de Todo o Mundo and flows for 30 km before flowing into the Óbidos Lagoon. A dam was built about one and a half kilometres from Óbidos, in the Horta Valley, whose reservoir was used to irrigate the area's crops.
