In the morning hours of 12 January 2021, the village of
Mikro Dereio was flooded and evacuated. Many houses including the central square of the village were flooded and local authorities were present in the area for hours. Residents managed to get inside the village church to save themselves. Schools in
Mikro Dereio were closed on the spot. At the same time, an iron bridge was destroyed by the water pressure in the village
Loutra near
Alexandroupoli. The bridge used to connect the two sides of the village. Warning signs were placed by the authorities of the
Municipality of Alexandroupoli. Few hours later,
Bulgaria opened up the
Ivaylovgrad Dam, releasing large amounts of water in the
Evros river.
Around 14:00,
the river of Erythropotamos started exceeding the expected levels and reached the top of the embankment around the river. In the meantime, the fields around
Metaxades started to flood.
Around 15:00, a bus carrying passengers from
Alexandroupoli to
Orestiada was trapped at the Feres agency, unable to go anywhere because of all the roads being blocked due to floods. Teachers that worked in
Alexandroupoli were unable to return to their home, and that resulted in them staying in
Feres and
Tychero all day.
Around 16:00,
Erythropotamos overflowed and embankments broke, causing severe damage to fields and properties around the area of many villages of the
Didymoteicho municipality. A few minutes later, the
General Regional Police Directorate of Eastern Macedonia & Thrace announced the cessation of traffic on the
National Road Ardaniou - Ormeniou (A21), from the settlement of
Provatona to the
District of Dadia.
Around 17:00, the village of
Poros was evacuated because of the overflow of the stream "Tsai" which led to the decision by the mayor of
Alexandroupoli, Giannis Zampoukis.
Around 19:00, the
Bulgarian Ministry of Foreign Affairs announced that in the next few hours an increase in the water level of the rivers
Arda and
Erythropotamos is expected following the gradual and controlled release of water from the
Ivaylovgrad Dam. A few minutes later, The Police Department of
Alexandroupoli decided to temporarily stop the traffic.
Around 20:30, the river level of
Erythropotamos has exceeded the vigilance limit and has reached 5.81 meters with an alarm limit of 7 meters. At this time, many villages in the area of
Erythropotamos flooded with severe damages in buildings and fields from powerful water pressure. The aqueduct in the area of
Alepochori went underwater and this led to the water being cut off for
Alepochori and
Polia. Other villages experienced the same water issue but it wasn't critical damage. In the meantime, the residents of the southern area of the village
Polia were forced to evacuate their houses because of a broken embankment in the area, allowing floods to speed up, and were taken by a bus to a hotel in
Didymoteicho temporarily, to prevent injuries and deaths.
Around 23:00, the road between the villages
Polia and
Avdella was cut in half due to water pressure. Under that road were optical fibers for internet and telephones, which were cut apart. That led to telecommunications being unavailable in
Alepochori. == Timeline of events on 1 February ==
