Hafik Lake

Hafik Gölü, one of the karstic areas of the Central Anatolia Region, is a natural freshwater lake located within the boundaries of Sivas Province. The lake is the subject of research and study due to its geomorphological features, archaeological findings, ecological diversity, and wetland status.

Among the settlement examples shaped by water sources, Hafik Gölü has yielded artifacts dating back to prehistoric periods at the Pılır Höyük site. This settlement has been documented as one of the earliest examples of above-water habitation evidence within Türkiye’s borders. The lake is also classified as a wetland under national protection and nominated for international conservation programs.

Hafik Gölü is situated 3 kilometers northwest of Hafik district in Sivas Province, within the Central Anatolia Region of Türkiye. The lake, located 36 to 40 kilometers from the provincial center, lies along the Sivas-Erzincan E-88 highway. With an average elevation of 1290 meters and a surface area of approximately 1 km², it is one of the largest natural lakes in the region. Of karstic origin, the lake formed in a depression area containing soluble gypsum rocks. Locally, the lake is also known as “Büyük Göl.”

The water of Hafik Gölü is fed by surface sources such as Sultanpınarı and Kapaklı, as well as groundwater rising from the lakebed. Excess water from the lake flows into the Kızılırmak River via the Köy Irmağı stream. This characteristic classifies the lake as part of an open basin system. The average depth of the lake is 6 meters, with a maximum depth of approximately 7 meters.

The lake reaches its maximum water level in spring; significant declines in water level are observed by the end of summer due to reduced rainfall. The lake consists of three distinct depressions, which in dry years separate into distinct water bodies. In spring, these depressions reunite to form a single water mass.

The lakebed is covered with mud and surrounded by extensive reed beds. Rich in sulfate salts, the lake hosts a rich freshwater ecosystem. Due to its natural structure, it is one of the areas where biological diversity is preserved. Around the lake, tree species such as pine, oak, and poplar coexist with shrubs including rosehip and barberry (Berberis vulgaris). The vegetation provides a natural habitat and breeding ground for birds.

Pılır Höyük, located within Hafik Gölü, demonstrates that the region was inhabited during prehistoric times. Archaeological excavations at the site have uncovered remains of lake dwellings built on wooden piles. This construction system represents the first and only known example in Türkiye of the “palafitte” above-water settlements previously identified in Lake Zurich and other Alpine lakes in Switzerland.

Among the findings are pottery from the Neolithic, Chalcolithic, and Early Bronze Age periods, flint microliths, obsidian (volcanic glass) leaf-shaped points, hand millstones, mallets, stone idols carved from sandstone, and animal bones.

The lake attracts attention for the diversity of life it supports within its freshwater ecosystem. Fish species found in the lake include carp, grass carp, crucian carp, tench, freshwater bream, blackfish, chub, bleak, and crayfish.

Hafik Gölü is among Türkiye’s 135 wetlands of international importance and is designated as an Important Bird Area (IBA). Approximately 150 to 200 bird species inhabit the lake and its surroundings. The main bird species recorded at the lake and its vicinity include:

Hafik Gölü is one of the leading nature-based recreational areas in Sivas Province. The lake’s surroundings feature picnic areas, camping zones, and facilities suitable for water sports. Visitors can engage in nature-integrated activities such as cycling along the shore, camping while reading, and birdwatching, as well as nature walks accompanied by the region’s native vegetation.

Hafik Gölü was officially registered in 2020 by the Ministry of Environment, Urbanization and Climate Change of the Republic of Türkiye as a “Natural Site – Qualified Natural Conservation Area” and a “Sustainable Conservation and Controlled Use Area.” The registration process for its designation as a “Strictly Protected Sensitive Area” is ongoing. It is also expected to be included under the international protection framework of the Ramsar Convention.

Under a project implemented by the Sivas Provincial Special Administration, nature-compatible walking trails, landscape arrangements, picnic areas, rest zones, and visitor-restricted areas are being constructed around the lake. The project aims to ensure controlled and conscious use of the area without damaging its natural structure.
