Abstract
Lake Bafa is one of the biggest coastal wetlands, which is located at the south-western part of Turkey. Its lagoon-like character makes it sensitive to hydrochemical changes. Here, in October 2006, mass fish mortality occurred and this disaster attracted public attention. Thousands of dead fish were observed at the north-eastern shores of the lake. Every institution undertook some researches and made evaluations regarding their responsibilities. However an overall systemic assessment was necessary to diagnose. Then the Ministry of Environment and Forestry initiated a comprehensive work taking geomorphology, biology, hydrochemistry into consideration together with the actual human use. At the beginning, the general opinion was that the main reason of this disaster was the heavy metal load of the lake. Conversely, our findings proved that this disaster happened because of a human induced chain reaction being completed with a local oxygen deficiency

Abstract
Bafa Gölü Türkiye’nin güneybatı kesiminde yer alan en büyük kıyı sulak alanlarından birisidir. Lagüne benzer özelliği gölü hidrokimyasal değişimlere karşı duyarlı kılmaktadır. Burada Ekim 2006’da bir toplu balık ölümü gerçekleşmiş ve bu olay kamuoyunun dikkatini çekmiştir. Gölün kuzeydoğu sahilinde binlerce ölü balık gözlenmiştir. Her kurum kendi sorumlulukları çerçevesinde araştırmalar gerçekleştirmiş, değerlendirmeler yapmıştır. Buna karşın doğru teşhis için genel sistemik bir değerlendirme gereklidir. Bu nedenle Çevre ve Orman Bakanlığı güncel insane kullanımını jeomorfoloji, biyoloji, hidrokimya ile birlikte ele alan kapsamlı bir çalışma gerçekleştirmiştir. Başlangıçta genel kanı facianın temel nedeninin gölün ağır metal yükü olduğu şeklinde olmuştur. Ancak bu çalışmanın bulguları facianın insan kökenli bir zincir reaksiyonunun yerel oksijen yetersizliği ile sonuçlanmasından kaynaklandığını ortaya koymuştur
