Water Quality Assessment of a Shallow Lake in a Specially Protected Area Lake Mogan Ankara Turkey

Kiraz, Melike
Alp, Emre
Mogan and Eymir Lakes are two shallow lakes, interconnected hydrologically in the close vicinity of Ankara, Turkey. A total of 245 km2 of the total 971.4 km2 watershed is under environmental protection status as ‘‘Go¨lbası Specially Protected Area’’. Potential impacts from extensive agriculture, recreation, incomplete infrastructure and other human activities, such as residential settlements, are discussed with reference to previous and more recent pollution monitoring. Six monitoring stations enabling follow-up of previous work were selected in this study. These were on the creeks feeding the lake systems. Generally, summer months showed heavier pollution loads, with Eymir Lake concentrating the pollutants due to flow from Mogan Lake. When compared with the 1995 study; COD, total-P, Kjeldahl-N in the six stations were close or slightly decreased in the present study. Suspended solids significantly decreased; possibly due to erosion control measures and decreased domestic wastewater. The improvement in the pollution state of the lakes is attributed to the construction of a sewage system going around Mogan Lake and collecting wastewater discharges and restrictions to urban settlement development around the lakes brought by the 1/25000 land use plan controlling further impact from residential developments within the protected area boundaries. The study, while addressing water quality and interactions due to human activities in shallow lakes, also discusses problems associated with human impacts in protected areas with the aim of presenting a complicated case study.

Sustainable management of Mogan and Eymir Lakes in Central Turkey
Yagbasan, Ozlem; Yazıcıgil, Hasan (2009-01-01)
Mogan and Eymir Lakes, located 20 km south of Ankara in Central Turkey, are important aesthetic, recreational, and ecological resources. Dikilitas and Ikizce reservoirs, constructed on upstream surface waters, are two man-made structures in the basin encompassing an area of 985 km(2). The purpose of this study is to quantify groundwater components in lakes' budgets and to assess the potential impacts of upstream reservoirs on lake levels for sustainable management of the system. Available data have been use...
Water-Food Nexus in Sakarya Watershed
Özel, Beyza; Başkan, Oğuz; Alp, Emre (null; 2019-06-19)
Sakarya River is the Turkey’s third longest river and the Sakarya watershed covers 8% of the surface area of Turkey. Significant agricultural activities accounts for most of the water withdrawals in the upper Sakarya Watershed. Within the scope of water-food nexus, water efficiency of agricultural irrigation have to be improved to aid sustainable water and agricultural management in the study area. The water potential and water uses were evaluated by Water Evaluation Planning System (WEAP) model in Upper Sa...
Palaeoenvironment and human interaction during the last 4k years in the dried lake sediments (amik lake, southern turkey): evidences of lake level changes
El Ouahabi, Meriam; Hubert-ferrari, Aurelia; Auwera, Vander; Avşar, Ulaş; Karabacak, Volkan (2019-02-01)
The Amik Basin in the Eastern Mediterranean region has been continuously occupied since 6000-7000 BC. The landscape has sustained with highly variable anthropic pressure culminating during the Late Roman Period when the Antioch city reached its golden age. The basin also sustained a high seismic activity (M≥7) as it is a releasing step-over along the Dead Sea Fault. The study focuses on the sedimentary record of the Amik Lake occupying the central part of the Basin. Our objective is to constrain major paleo...
Integrated Watershed Management for Lake Mogan with the focus of Agricultural Diffuse Pollution
Özcan, Zeynep; Başkan, O; Düzgün, Hafize Şebnem; Kentel, Elçin; Alp, Emre (2015-09-25)
Lake Mogan located 20 km south of Ankara, Turkey has a watershed area of 970 km2, and it is dominated by areas with dry agricultural practices (50%) and graze lands (31%). Intense agricultural activities and fast urbanization rates are the most important factors affecting the water quality in Lake Mogan. There has been several management alternatives suggested to improve the water quality in Lake Mogan. In 2008, the municipality implemented lake augmentation strategy to increase the water level since it dro...
Evaluation of the best management practices to control agricultural diffuse pollution in lake mogan watershed with swat model
Özcan, Zeynep; Alp, Emre; Kentel Erdoğan, Elçin; Department of Environmental Engineering (2016)
Lake Mogan which is located in Gölbaşı County, Ankara, Turkey is one of the most important wetlands of Turkey and it was declared as Special Environmental Protection Region in 1990. Total area of semi-arid Lake Mogan watershed is 970 km2 and dry farming is practiced approximately in 40% of the basin. Therefore, agricultural diffuse source pollution is a serious concern in the watershed. In the context of this thesis, the effects of implementation of different agricultural best management practices on sedime...
