River
The Aliakmon River, stretching approximately 297 kilometers, is the longest river located entirely within the borders of Greece. It originates in the Grammos Mountains near the Albanian border and flows through the regions of West and Central Macedonia before emptying into the Thermaic Gulf. The river is a cornerstone of the Greek economy, particularly due to the Polyfytos dam, which is utilized for large-scale hydroelectric power generation and irrigation. Geologically, the Aliakmon has deposited sediment over millennia to form fertile plains that support the backbone of regional agriculture. Its delta is a protected wetland of high ecological significance, providing a sanctuary for numerous migratory birds and endangered species. Historically, the river often served as a strategic boundary and was mentioned by ancient historians such as Herodotus. Maintaining the water quality of the Aliakmon is essential for both agricultural needs and the supply of drinking water to nearby urban centers.
