Pamukluk Dam (Turkish: Pamukluk Barajı) is a water‑storage and regulation structure located on the Pamukluk River in the Gülnar district of Mersin Province, southern Turkey. The dam is managed by the General Directorate of State Hydraulic Works (DSİ) and serves multiple purposes, including irrigation, municipal water supply, flood control, and modest hydroelectric power generation.
Location
The dam is situated in the Taurus Mountain region, approximately 60 km east of the provincial capital Mersin. It impounds the Pamukluk River, a tributary of the Göksu River, within a relatively rugged watershed characterized by steep valleys and a Mediterranean climate.
History and Construction
- Planning and Approval: The project was incorporated into Turkey’s national water‑resource development plans during the early 2010s.
- Construction Period: Ground‑breaking took place in 2012. The main civil works were completed and the reservoir began filling in 2020, with full operational status achieved shortly thereafter.
- Funding: Construction was financed primarily by the Turkish state through the DSİ budget, supplemented by regional development funds.
Purpose and Functions
- Irrigation: The reservoir provides water for the irrigation of agricultural lands in the surrounding district, supporting crops such as citrus, olives, and greenhouse vegetables.
- Municipal Water Supply: It supplies potable water to the town of Gülnar and nearby villages.
- Flood Control: By regulating river flow, the dam reduces the risk of downstream flooding during the rainy season.
- Hydroelectric Power: A small-scale hydroelectric plant installed at the dam’s outlet generates electricity, contributing to the local grid; the installed capacity is on the order of a few megawatts.
Design and Technical Characteristics
The dam is an earth‑fill embankment structure with a concrete spillway. Detailed technical specifications (e.g., precise height, crest length, reservoir total storage volume) are not widely published in open‑access sources; therefore, exact figures cannot be confirmed without access to DSİ technical reports.
Operation and Management
The DSİ is responsible for the dam’s operation, maintenance, and water‑resource allocation. Regular monitoring includes reservoir level management, inspection of embankment integrity, and coordination with agricultural agencies for irrigation scheduling.
Environmental and Social Aspects
The creation of the reservoir led to the submergence of a limited area of forest and arable land, prompting resettlement measures for affected households. Environmental impact assessments conducted prior to construction highlighted the need for fish passage and sediment management to mitigate downstream ecological effects.
