The river's water levels reach their highest state from February - March and July - August, whereas they are lowest from September - October.

Several other waterways, such as the Mala Panew, Żydówka, Brynica, Jemielnica, Swornica, and Brzeziczanka form a vast river network in the area, in addition to numerous streams.

The Brynica and Odra rivers are characterized by relatively flat surrounds, thus the Dobrzen Wielki area is susceptible to flooding.

In 1658, the Church of St. Roch (Kosciol Sw. Rocha) was constructed, following the invasion of the Norbertine monastery by Protestant armies in 1643.

The history of Dobrzeń Wielki was always linked to the Duchy of Opole which broke away from Poland and came under the rule of Bohemia in 1327, fell to the Habsburgs in 1526, became Prussian after the First Silesian War in 1742 and had been part of Germany since 1871.
