The Ogre River is a significant tributary of the Daugava, which historically was a salmon and lamprey river. However, after the construction of the Riga HPP, migration of these fish from the sea has ceased. The river itself has 3 HPP dams, but suitable habitats for these sensitive fish species have been preserved.

The Ogre River is a significant tributary of the Daugava, which historically was a salmon and lamprey river. However, after the construction of the Riga HPP, migration of these fish from the sea has ceased.
There are 3 HPP dams on Ogre river, but local fish populations have been preserved, making it a potentially important site for salmon and lamprey reintroduction.
Key protected species:
LIFE RiverFlow restores Latvia's river ecosystems — removing barriers, reconnecting fragmented rivers and building nature-friendly fish passages so rivers can flow freely again.
