The river mouth acts as a natural division between the municipal jurisdictions of Balneário Piçarras and Penha.
The area is a key site for the local 'pesca artesanal' (artisanal fishing) culture, which remains a central economic activity for the local community.
The riverbed depth at the mouth is periodically managed via dredging projects to ensure the passage of local fishing boats.
The confluence of the river and ocean creates a specific brackish water habitat, influencing the local biodiversity of fish and crab species.
Barra do Rio Piçarras is the geographic point where the Piçarras River meets the Atlantic Ocean, acting as the natural maritime border between the municipalities of Balneário Piçarras and Penha. The area is characterized by a mix of fluvial and marine ecosystems, creating a calm harbor environment protected from the direct force of Atlantic swells. It serves as a primary access point for local artisanal fishing fleets and leisure watercraft navigating toward the open sea. The northern bank falls within Penha, while the southern side belongs to Balneário Piçarras. The location is a hub for nautical activities, including rowing and fishing, and features a specialized maritime infrastructure. Recent environmental maintenance has focused on dredging to keep the river mouth navigable for local vessels.
