Virtually the entire river flows along the Lowland of Central Latvia (
Latvian: ''Viduslatvijas zemiene'').
The river meanders through a wooded area, the pool is heavily drained in some places. The shores are generally flat, with occasional Devonian bare rocks. There are many floodplains in the lower reaches of the mouths of rivers Krievupe and Tumšupe.

From Sidgunda to Ropaži the river is 5-15 m wide. In and around Ropaži, the regime of the river is determined by the operation of the local hydroelectric power station (HES), where the river is crossed by a dam - a 1.5 m high concrete wall, which creates an artificial waterfall.

/ref> A 1.5 km long left outflow begins at the dam, which forms an island with Ropaži Park and the municipality council on it. After the HES the river is calm and shallow in low water, before Bajāri begin thresholds and the river reaches a slope of 3.5 m/km. The thresholds end at Zaķumuiža, then the flow calms down again. At the mouth of Jugla Lake it meets the Mazā Jugla River, forming the Jugla River, the sediments of which as Jugla Delta penetrate deeply into the lake.
