Lika (river)

The Lika is a river in the Lika region of Croatia. It is a karst river, meaning it flows through porous limestone bedrock, and is known for its intermittent flow and subterranean passages. The Lika is approximately 78 kilometers (48 miles) long, making it the second-longest sinking river in Croatia, after the Trebišnjica.

The river originates in the southern part of the Lika region, near the border with Dalmatia, from several springs near the village of Homoljac, close to Gračac. It flows generally northward through a series of karst fields (poljes), including the Licko Polje, before disappearing underground near the village of Ponor. The Lika's waters eventually resurface further downstream, contributing to the Gacka River.

The Lika River has been dammed at several points for hydroelectric power generation. These dams have created several artificial lakes along its course, including Lake Krušćica.

The Lika River is significant to the Lika region, providing water resources and contributing to the local ecosystem. However, its karst nature makes it vulnerable to pollution and necessitates careful management to ensure its long-term sustainability.
