FWC-NbS 2: Natural wetland complex (Type A+C)
Location: Amyntaio, Greece
Climate: Hot-summer Mediterranean climate
Area: 960 Ha
Objectives: Improve water quality and storage of natural wetland and its distribution system.
Challenges: Seasonal dry; groundwater level decrease; eutrophication; reeds overgrowth; water pollution and run-offs; silting
Description: Lake Chimaditida is a shallow lake that together with Zazari, Petron and Vegoritida lakes form a connected lake complex. It is surrounded by two small hills and a large crop area created by extensive drainage works. Large seasonal wetlands are formed in the meeting areas with the fields. The flora and fauna of the area is very rich: is the most important breeding ground for the endangered species Aythya nyroca and it provides an important habitat for birds and rare flora species. The lake has a eutrophic character and depending on the hydrological, climatic and biological factors, it can range from mesotrophic to hypertrophic character. It belongs to EU Natura 2000; *SPA; **SAC. Connecting canals between lakes and a peripherical dyke was built to protect agricultural land.
Riparian buffers will be implemented in part of the lake to cope with the pressure the lake is under due to agricultural activities (irrigation, pesticide run-off, etc.). The lake can vary from mesotrophic to hypertrophic depending on the phase of the water cycle.
In the study area, there are and operate two collective irrigation networks (shown in Black and Green on the Map) that draw water from Lake Zazari, directly opposite Lake Chimaditida, and the consumption of this water has a particular impact on the water balance of the Lake Chimaditida. While almost the entire area on either side of the drainage ditch is irrigated by water withdrawals from the farmers. The integrated management of the irrigation of this area will help to reduce consumption.
In order to monitor the effect of the natural systems on Lake Chimaditita, physicochemical parameters should be observed and measured. There should be a full assessment of the quality characteristics of the lake by mapping them to reference points. And correlation both with each other and with their automatic measurement station.
