The water power of the Krka River attracted many industrialists here to build hydroelectric plants and other production plants. Along the river's course are three hydroelectric plants constructed at the turn of the 20th century: HEP Miljacka under the Miljacka waterfall, HEP Roški slap at Roški slap and HEP Jaruga at Skradinski buk, which is still in function and producing electricity today. The remnants of the fourth, and oldest hydroelectric plant, HEP Krka, is also at Skradinski buk. The plant has been systematically researched, and conservation works and its partial reconstruction are underway. Due to its historical significance, the plant is a monument of industrial architecture, and is protected as a cultural good of the Republic of Croatia.
