Lake Eymir (39\u25e6570 N, 32\u25e6530 E) and Lake Mogan (39\u25e6470 N, 32\u25e6470 E) are at 20 km south of Ankara, Turkey and at an altitude of 970 meters and Lake Eymir located in Middle East Technical University campus since 1956. In 1997, Lake Mogan was abundant in aquatic plants and had low chlorophyll-a (Chl-a) values (8.8 \u00b1 2 \u00b5g\/L) and average total phosphorus (TP) concentration (63 \u00b1 5 \u00b5g\/L). Lake Eymir was clean enough to meet the drinking water needs of Middle East Technical University before 1970s. However, between 1970 and 1995, there was a deterioration in water quality in both lakes by the introduction of untreated sewage into the lakes. In 1995, a system was established for the treatment of waste water, and the wastes of a few restaurants around Lake Mogan were controlled and the phosphorus input was reduced by 88% by then. Lake Eymir and Mogan ecological monitoring research programme was continued for 23 years by METU-Limnology Laboratory and Ecosystem Research and Implementation Center (EKOSAM) and it is the first and only long-term and continuous work for freshwater research done in Turkey. Thanks to these studies, effective restoration studies have been carried out to reduce eutrophication in these lakes. Hydrological data, which are very important for lake ecosystems, could be followed in detail by these long-term studies. Moreover, a high frequency automated system was established in Lake Eymir in 2015.","citation":null,"relatedIdentifiers":null,"status":null,"yearEstablished":null,"yearClosed":null,"relatedSites":null,"siteName":"Lake Eymir and Lake Mogan","shortName":"Eymir and Mogan","siteType":null,"protectionLevel":null,"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/2020-07\/eymir%20mogan.png","alt":"Map of Lake Eymir and Mogan"}]},"environmentalCharacteristics":{"airTemperature":{"yearlyAverage":12,"monthlyAverage":null,"unit":"\u00b0C","referencePeriod":null},"precipitation":{"yearlyAverage":408,"monthlyAverage":null,"unit":"mm","referencePeriod":null},"biogeographicalRegion":"anatolian","biome":null,"ecosystemType":[{"label":"Agricultural","uri":null},{"label":"Forest","uri":null},{"label":"Fresh Water Lakes","uri":null},{"label":"Lakes","uri":null},{"label":"Small lakes","uri":null},{"label":"Urban","uri":null}],"eunisHabitat":[{"label":"Buildings of cities, towns and villages (J1)","uri":null},{"label":"Constructed, industrial and other artificial habitats (J)","uri":null},{"label":"Habitat complexes (X)","uri":null},{"label":"Inland surface waters (C)","uri":null},{"label":"Regularly or recently cultivated agricultural, horticultural and domestic habitats (I)","uri":null},{"label":"Woodland, forest and other wooded land (G)","uri":null}],"landforms":null,"geoBonBiome":["Fresh water lakes"],"geology":"Quaternary land\r\nConglomerate layers\r\nLimestone\r\nPermien Graywacke\r\nPermo-carboniferous\r\nEpi-metamorphic","hydrology":"Lake Mogan, which is located above, is fed both from groundwater and surface water, and it has 4 main streams flowing throughout the year, 3 of which are inflows and 1 is outflow, and many lots of short-lived streams.
