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.

This area, which is home to vast meadows, owes its name to the fact that in the past (80 or 90 years ago) it was a place where wild cattle were allowed to graze freely. Next to a small lake created to retain rainwater (surface water is rare in the Serra de Montejunto, as it is a mountain made up mostly of limestone), you can still see the ruins of an old stable where the animals spent the night to protect themselves from the cold. Today, this area, especially in the autumn and winter months, is used as a grazing area for goats and sheep. In the spring and summer, these fertile meadows are used by the populations of the nearby villages (Cercal and Rocha Forte) to grow crops such as potatoes and other dryland crops.

Opened in 2005, this dam never fully served the purposes for which it was created. After recent works (2022/2023), it is now expected that it will be able to serve farmers in the region with water for irrigation and even be used for leisure purposes. The surrounding region has interesting paths for mountain biking or gravel cycling.

Built in 1997, the Sobrena (Cadaval) dam never filled. It was expected to irrigate 100 hectares of agricultural land, benefiting 120 farmers, mainly Rocha pear producers. The dam is an exposed ruin, with the support buildings invaded by brambles and a wall from which a pond can be seen in the place where a reservoir should have been. All around you can see eucalyptus trees. And these trees are precisely one of the reasons for the failure of this investment of more than two million euros.
