Flag description: Yellow with a green garuly diagonal stripe from
hoist-bottom to fly-top, and in hoist top a red lying brick.
Explanation: the garuly stripe is derived from the stump on the Mellema
family Coat of Arms. The diagonal division refers to Oostdongeradeel's Coat of Arms, and
the brick to the old brick-factory.
Oostrum (Frisian: Eastrum) is a village with (1-1-1999) 189 inhabitants
at 3 km east of Dokkum. It used to be important because of the brick-factory
('it Stienfek') and the ZPC-building for storing potatoes (mainly).
Both are now used for yachting purposes.
