On the E side a breakwater extends 2 cables NNW to Górki Wschodnie Light (54°22,5'N, 18°46,7'E). on the W side, a breakwater extends 1 cable N and a submerged groyne, 3 cables W of the entrace, extends 2 cables NNE, Its extremity is marked by a booy (N cardinal).
The costal bank, on which there is a tongue-shaped sandbank with depths of less then 5 m over it, etends about 1¼ miles NNW from the river mouth. The sandbank is subjected to frequent changes after stormy weather.
