Abstract

Karacaören I Dam Lake is located in the South-Western Mediterranean of Turkey. Although it has been established for energy, flood control, and irrigation, it is also used for fishing and recreational activities. An intense algal bloom was observed at the riverine zone of Isparta and Göksu streams, two important sources feeding this reservoir. The phytoplankton bloom was observed in the early spring as a dense reddish-brown band at the riverine zone of Isparta Stream and Göksu Creek were mixed into the reservoir. Visually, it was determined that the intensity of algal bloom decreased from the riverine zone to the lacustrine zone of the reservoir. On 18 March 2014, the organism causing the bloom in the plankton and water samples was determined to be Peridiniopsis cf. cunningtonii (Lemmermann) Lemmermann from Dinoflagellata. The maximum cell density of species was determined as 26,997 cells/ml in the mouth of Isparta Stream and 22,262 cells/ml in the mouth of Göksu Creek. Besides, intense fish deaths were observed at these dates during an algal bloom. Based on these results, it is predicted that especially urban wastes from Isparta Stream and fish farming wastes from Göksu Stream may trigger algal blooms in the reservoir, and this situation may occur in the future.

Özet

Bu çalışmada, Türkiye'nin batı Akdeniz Bölgesi’nde yer alan; enerji, taşkın kontrolü ve sulama amacıyla kurulmuş olan, ayrıca balıkçılık ve turizm faaliyetleri için de yararlanılan Karacaören I Baraj Gölü’nü besleyen iki önemli kaynak olan Isparta Çayı ve Göksu Deresi’nin baraj gölüne karışım noktasında aşırı alg çoğalmaları (fitoplankton patlaması) incelenmiştir. Yoğun algal gelişim, ilkbahar başlarında Isparta Çayı ve Göksu Deresi’nin baraj gölüne karıştığı nehir ağzı bölgesinde kızıl-kahverengi belirgin bir bant olarak gözlemlenmiştir. Görsel olarak, alg patlaması yoğunluğunun nehir ağzı bölgesinden lakustrin bölgeye doğru azaldığı kaydedilmiştir. 18 Mart 2014’de bu ortamdan alınan plankton ve su örneklerinde plankton patlamasına neden olan organizmanın Dinoflagellata’dan Peridiniopsis cf. cunningtonii (Lemmermann) Lemmermann olduğu tespit edilmiştir. Bu türün en yüksek yoğunluğu Isparta Çayı ağzında 26.997; Göksu Deresi ağzında ise 22.262 hücre/ml olarak belirlenmiştir. Ayrıca alg patlamasının tespit edildiği sırada yoğun balık ölümleri gözlemlenmiştir. Bu sonuçlardan hareketle, özellikle Isparta Çayı’ndan gelen kentsel atıkların ve Göksu Çayı’ndan gelen balık yetiştiriciliği atıklarının baraj gölünde alg patlamalarını tetikleyebileceği ve bu durumun gelecekte de ortaya çıkabileceği öngörülmektedir.
