Kızılçan Lake

Kızılçan Gölü is a collapse doline lake formed within the boundaries of Canova Village in the Zara district of Sivas Province, situated in a gypsum karst region. Located within the Upper Kızılırmak Basin, the lake constitutes one of the region’s characteristic karstic landforms due to its distinctive turquoise color and circular shape.

The formation of the lake is directly linked to the gypsum (calcite) karst widely found along the Sivas-Zara corridor. Classified scientifically as a collapse doline, Kızılçan Gölü resulted from the dissolution of gypsum layers by groundwater and the subsequent collapse of the overlying rock stratum. According to academic measurements, the lake has a nearly circular perimeter with a diameter of approximately 300 meters and a depth of 50 meters.^【1】 The area where the lake is located has also been shaped by tectonic activity; Kızılçan Gölü, along with other nearby karstic features such as Akgöl and Karagöl, aligns in a linear pattern following a tectonic fault line. Although local populations sometimes assume the lake to be a volcanic crater, scientific data confirm its gypsum karst origin and collapse doline structure.^【2】

Kızılçan Gölü is fed by groundwater sources emerging from its bed. Seasonal fluctuations in water levels are observed in response to precipitation patterns and drought conditions. It is believed that the lake’s water is connected underground to other nearby collapse dolines such as Karagöl and Akgöl to its west. In this region dominated by a continental climate, winter temperatures frequently drop below freezing, causing the lake surface to freeze completely and become covered by a layer of ice.

Located approximately 50 kilometers from the center of Sivas Province and 2 kilometers from the center of Canova Village, the lake is one of the natural protected areas assessed under the first phase of the “Upper Kızılırmak Culture and Nature Route” project. Due to its circular shape when viewed from above and the distinctive color of its waters, the lake is frequently described in literature and local media as resembling a “nazar boncuğu” (evil eye bead).^【3】 While the lake holds potential for photography and nature observation, it currently lacks comprehensive tourism infrastructure. However, local authorities have planned road and environmental improvement projects to enhance accessibility and preservation.
