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. In October 2006, mass fish mortality occurred and this disaster attracted public attention.

Many institutions undertook 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. In the beginning, the general opinion was that the main reason of this disaster was the heavy metal load of the lake. The findings proved that this disaster happened because of a human-induced chain reaction being exaggerated by a local oxygen deficiency.

Still today that chain reaction is continuing and now the lake is at a critical point to avoid the repeat of mass fish and bird mortality the balance of the lake must be helped. This should be undertaken nationally and by the two local authorities Mulga and Aydin. We at Lake Bafa Org want to keep the pressure on the agencies that are responsible for this by constantly keeping the issues and this location in both the publics and governments mind.

The Lake Bafa is an alluvial bar lake located in the Aegean Region in the Big Meander river basin in Aydın and Mugla provinces. However, the lake is currently threatened by severe pollution, being under the risk of serious degradation because of (i) uncontrolled urbanization; (ii) point and non-point source pollution; (iii) algae bloom; (iv) sediment transportation and pollution via influent creeks to the lake; and (v) severe degradation of the natural wetlands within its drainage basin. In this study, the water samples were taken from 8 different stations which were inside and the shores of the Lake Bafa in February 2009, 2010 and August 2009, 2010. The stations that were spotted in the lake were analyzed for the physical and chemical changes taking place in water quality. Temperature, pH, EC, CO3, HCO3, Cl-, NO2, NO3, DO, o-PO4, Na, K+, Ca2+, and Mg2+ parameters were measured. In the analyses, August and February months were chosen and their pollution loads were compared. Because of the fact that tourism activities generally increase in Lake Bafa, especially in August, domestic water discharges go up. Therefore, these rises cause the pollution load in the lake in August. On the other hand, Lake Bafa just serves for fishing boats in February, so the pollution rate in February is not as much as in August within Lake.

In other words, water pollution in August is higher than pollution in February
