The lakes Koroneia and Volvi are located in ​​Central Macedonia between the mountains Vertiskos and Holomondas. Both Koroneia and Volvi are the residual basins of lake Mygdonia that occupied the region millions of years ago. Over the years the waters receded creating the current morphology of the terrain with the two lakes.

 

Koroneia

Koroneia, also known as lake Lagada, occupies the western part of the valley. By the late 1907, Koroneia was occupying an area of ​​45,000 acres with a maximum depth of 5 meters . By that time, it was the fifth largest lake in the country. The following years, the water level dropped to such an extent resulting in desiccation twice, in 1999 and 2007. The diversion of the nearby rivers to the lake increased the water supply. Today, the  water depth of the lake  is almost 2 meters. The waters of the lake travel through pipelines and canals to the lake Volvi.

The ecosystem of the area is poor and hostile for the migratory birds, that prefer the lake Volvi. Environmental degradation is intense due to channel sewage and toxic waste in the lake during the previous decades.

 

Volvi

Lake Volvi is an elongated basin, directed from East  to West, which occupies the eastern part of the plain of Mygdonia. Volvli is the second largest lake of Greece occupying an area greater than 68 square kilometers. The maximum depth is greater than 23 meters while the maximum length of the lake reaches 19.5 km.

Volvi is supplied with water and sediments  by Koroneia lake to the West and the mountains Kerdylio and Holomondas. The waters of the lake end up to the sea, in the Strymonikos gulf.

The rich fauna includes 23 species of fish. Among those are Liparia and Lakopsaro that cannot be found nowhere else in the world. More than 200 species of birds have been observed in the broader area of the lake. The biodiversity of the  birds increases with the seasonal influx of migratory species.

The waters of the lake are used to irrigate farmland and for the development of aquaculture. The last years, a decline in the water level has been recorded. Finally,  the human activities downgrade rapidly the natural environment.
