Daugava River Mouth
The Daugava river mouth near Riga is a geographically and ecologically sensitive area where Latvia's longest river enters the Baltic Sea. The delta includes extensive reed beds, sandbanks, and the historical Mangaļsala mole, constructed between 1850 and 1861. This region serves as a critical corridor for migratory fish species such as salmon and sea trout, which move upstream to spawn. Botanically, the delta is known for its halophilic plant communities adapted to fluctuating salinity levels. Historically, the mouth was the strategic gateway to the Port of Riga and was secured by fortifications like the Daugavgrīva Fortress. Today, the area is a popular destination for ornithologists as it lies on the Baltic flyway for millions of migratory birds. Monitoring sediment dynamics is of central importance for shipping and coastal protection.
