Dolphins spotted in Szczecin: rare observation near the Pioneers’ Bridge ahead of Christmas

Just days before Christmas, an exceptionally rare environmental event was recorded in north-western Poland. Cameras operating within the river information system (RIS) captured footage of two large aquatic mammals in the vicinity of the Pioneers’ Bridge in Szczecin, on one of the branches of the Regalica River, part of the Szczecin waterway junction.

Dolphins in inland waters: an extraordinary phenomenon

The recordings were obtained from monitoring infrastructure managed by the inland navigation office in Szczecin, responsible for vessel traffic and river safety in the region. The video material shows two fully grown individuals, swimming together and remaining visible for a short period within the monitored section of the river.

While scientific caution remains essential due to the limitations of remote observation, the animals’ size, movement patterns and surfacing behaviour strongly suggest that they were dolphins rather than other large aquatic species. Their presence in the Regalica River represents a phenomenon of exceptional rarity in Poland.

Environmental and navigational significance

Dolphins are only sporadically observed in the southern Baltic Sea, and sightings in Polish inland waters are virtually unprecedented. Their appearance within the Szczecin waterway junction raises important questions for marine biologists, hydrologists and environmental policymakers.

Experts indicate that such events may be linked to:

• climate-driven changes in marine ecosystems,
• shifts in migration routes of marine mammals,
• temporary improvements in water quality,
• navigation-related disorientation or pursuit of prey species.

From a maritime and inland navigation perspective, the observation also highlights the increasing importance of integrated monitoring systems, such as RIS, not only for transport safety but also for environmental surveillance.

A symbolic event ahead of Christmas

The timing of the sighting – just before Christmas Eve – has given the event a symbolic dimension. In a region where winter snowfall has become increasingly rare, the unexpected presence of dolphins has been widely perceived as a unique “gift from nature”.

Often regarded as ambassadors of marine ecosystems, dolphins are associated with intelligence, adaptability and environmental balance. Their brief appearance in Szczecin provided residents and observers with a moment of reflection on the interconnectedness of marine and inland water systems.

Dolphins instead of snow

Although further expert verification would be required for absolute certainty, one conclusion is clear: if dolphins indeed entered the waters of the Regalica River, the event stands as one of the most remarkable wildlife observations in the recent history of Polish inland waterways.

Their short-lived presence delivered not only an extraordinary visual record but also a strong message about the dynamic changes currently affecting European waters – a message particularly resonant at the threshold of the Christmas season and the approaching New Year.

Dolphins in Szczecin spotted thanks to Oder River monitoring

The rare appearance of dolphins in Szczecin was captured by the River Information System, operated by the Inland Navigation Office. This integrated monitoring system, featuring 52 cameras along the Oder River, transmits real-time footage to the River Information Centre in Szczecin. It ensures safe and efficient navigation by providing up-to-date hydrological, navigational, and weather data.

Beyond supporting river traffic, the camera network occasionally records extraordinary natural events, such as dolphins swimming in the heart of the city, highlighting the dual role of Oder monitoring in both safety and observation of wildlife.
