Bourgas Lake (Vaia)
February 3rd, 2009 by michelle
Bourgas Lake, also called Vaia, is one of the three lakes that surround the coastal city of Bourgas as a ring.
The lake is an open coastal firth, situated west of Bourgas. It is the biggest natural lake in Bulgaria. The surface area is 28 sq km and the length and width reach respectively 9.6 and 4.5 km. Vaia is quite shallow and its depth is 1.3 m. Because of that shallowness, the lake is sometimes called a swamp. A channel connects Vaia to the Black Sea. The saltiness of the lake’s water varies from four to 11 percent.
Aitoska, Sunder Dere and Choukarska rivers provide the lake with water. During the summer, sea water enters it. Clay deposits cover its bottom.
Several small swamps are situated north of the lake. Breeding pools were constructed in the northwestern part. The eastern part of the lake neighbors industrial and residential Bourgas areas.
Vaia’s shores feature numerous plants among which reed and rush. Marshlands and agriculture territories surround the water.
One of the biggest bird migration routes, Via Pontica, passes over Vaia. In 2003, the lake was named an area of international importance.
Parts of the lake were named a protected area, aiming to preserve a large number of bird species nesting there.
More than 20 types of fish and 254 types of birds can be observed in the region. Apart from nesting birds, tourists can observe some species that rest there during their migration period. As a result, Vaia was named an ornithological spot of European importance.
In 2001, the channel connecting the lake to the sea was cleaned, allowing sea fish to enter Vaia. This provided suitable fishing conditions. Yet, the fish that is most often caught there is carp.
Over the past few years, students gather in the region during August and work on the creation of pelican nesting platforms. They have also set up shelters for bird watching.
Vaia features other opportunities for nature preservation or pleasant leisure time. Tourists can benefit from boat walks, allowing them to observe and photograph bird species. Observing all the pelicans and herons is truly one unforgettable experience. Opportunities for eco tourism in the region are constantly created.
The proximity to Bourgas provides additional spots for rest, accommodation and entertainment.
Ropotamo preserve is situated 50 km south of the coastal city of Bourgas. It includes the banks of Ropotamo River. Ropotamo is one of the oldest preserves in Bulgaria, named as such in 1940.
