The river Ogre flows through Madona, Ērgļi, Vecpiebalga, Lielvārde, and Ogre Municipalities. The river is 188 km long with an elevation of 222 m, the biggest tributaries are Līčupe and Aviekste. The river discharges into the river Daugava (GPS [56.8127, 24.6079]). The river Ogre is the third longest river in Latvia, and it have never been dredged. In 2003, experts of the Latvian Fund for Nature found a significant concentration of specially protected biotopes and plant species at the river Ogre. There are 15 specially protected biotopes in Latvia found at the river valley. The banks of the river directly show the north and south directions, therefore the microclimate on each bank differs. It is possible that while on one side there is already green grass, the snow can still be seen on the other side of the river. In several places dolomite outcrops can be observed on the banks of the river: Kalnrēži Dolomite Sandstone near Rembate and the Dolomite Slope near the old cardboard mills  in Ogre are protected geological objects. The river can be used for boat trips all season long starting from the place where the Ogre Hydropower Station once stood (near the station Baltava), and at higher water levels – from Ērgļi, and during the seasonal flood you can travel even from the lake Inesis along the tributary Sustala.
