The Emajõgi (Estonian pronunciation: [ˈemɑ.jɤgi]; meaning 'mother river') is a river in Estonia which flows from Lake Võrtsjärv through Tartu County into Lake Peipus, crossing the city of Tartu for 10 km (6.2 mi). It has a length of 100 km (62 mi).
The Emajõgi is sometimes called the Suur Emajõgi (Big Emajõgi), in contrast with the Väike Emajõgi (Little Emajõgi), another river which flows into the southern end of Lake Võrtsjärv.
The Emajõgi is the second-largest river in Estonia by discharge and the only fully navigable river.
Course
The source of the Emajõgi is at the northeastern shore of Võrtsjärv at Rannu-Jõesuu, from where the river follows a roughly eastward course towards Lake Peipus.
The course of Emajõgi is divided into three distinct sections. In the upper course, from Võrtsjärv to Kärevere bridge, the river flows through large, flat and marshy areas, which are part of Alam-Pedja Nature Reserve. In this heavily meandering section, Emajõgi lacks a clearly defined floodplain – the flooded area spans several kilometres at times and has no definite borders. In the middle course from Kärevere to Kavastu through Tartu, Emajõgi follows a straighter course and flows in a clearly defined, shallow valley mostly a maximum of 10 m (33 ft) deep. The width of the valley in the middle course is 1–1.5 km (0.62–0.93 mi); in Tartu, it narrows to 800 m (2,600 ft). The narrowest section of the valley (400–600 km (250–370 mi)) is located in the end of the middle course near Kavastu. In the lower course, the river flows through a swampy lowland – Emajõe Suursoo – before emptying into Lake Peipus at Praaga.
The length of the river is 100 kilometres (62 mi). In 1927, its length was measured to be 117 kilometres (73 mi). This may have changed somewhat in the 1930s, when the river's meandering upper course was straightened to allow for easier navigation.

History
The Emajõgi has been widely used as a waterway and trade route for centuries. In the past, it has also been an obstacle for land transport between Northern and Southern Estonia, because the river flows in a low-lying and swampy valley. Of the few suitable locations for crossing the river, Tartu has the most favourable conditions. Due to its location on the crossing of land and water routes, Tartu became an important trading center in Ancient Estonia.
In the 19th century, Emajõgi was actively used for transporting different cargo to Tartu – firewood, timber, hay, fish, and so on. The main type of vessel used was the lodi, a small river barge or sailing ship adjusted for navigation on Lake Peipus and Emajõgi. Up to 200 barges were anchored in Tartu's port at the time. The first steam paddler appeared on Emajõgi in 1843; there were six by 1900. The last river barges disappeared by the mid-20th century, however several new ships were brought onto the river to continue naval transport to Pskov, Piirissaar and other destinations. Fast hydrofoils, which were first introduced in 1960s, operated daily on the Tartu-Pskov route. Traffic on the route ended in 1992. Though attempts have been made to restart it since 1997, it remains closed.
Crossings
Emajõgi is crossed by 10 bridges, the majority of them located in Tartu. The bridges are, in downstream order:
- Rannu-Jõesuu bridge at the source of Emajõgi on Tartu–Viljandi highway
- Includes an old bridge currently reserved for pedestrians and local traffic and a new highway bridge completed in 2009.
- Kärevere bridge on Tartu–Tallinn highway
- Includes a closed old bridge and a new highway bridge completed in 1999.
- Jänese railway bridge on Tallinn–Tapa–Tartu railway 7 km northwest of Tartu in Vorbuse
- Kroonuaia bridge in Tartu
- Vabadussild in Tartu peedu
- Vabadussild
- Kaarsild – pedestrian bridge in Tartu
- Võidu bridge in Tartu
- Turusild – pedestrian bridge in Tartu
- Sõpruse bridge in Tartu
- Ihaste bridge on the Tartu ring road, opened in 2015
- Luunja bridge on Tartu–Räpina highway in Luunja
In addition to the bridges, the only operating cable ferry in Estonia crosses the river at Kavastu, about 10 kilometres (6.2 mi) downstream of Luunja bridge.
