Issyk-Kul deep water monitoring, June 2018
From June 12 till June 15, 2018 the State Agency of Environment Protection and Forestry under the Government of the Kyrgyz Republic (SAEPF) and Agency on Hydrometeorology (Kyrgyzhydromet) under the Ministry of Emergencies Situations of the Kyrgyz Republic with participation of the Finnish Environment Institute under the Project’s support has organized and conducted deep water monitoring of Issyk-Kul Lake.
The deep water monitoring includes the set of water samples studies. The water samples from the deepest points are taken from the scientific-research vessel Moltur. Water sampling from the area of Tup gulf and Balykchy town, where sampling points are located at the distance not far than 200 meters from shoreline is implemented from the motor boat (procured within the project in order to optimize lake monitoring process). Sampling from motor boat simplifies and facilitates the monitoring process significantly.
Issyk-Kul lake water sampling has been fulfilled by the specialists of Environmental Monitoring Unit of Issyk-Kul Territorial Administration of SAEPF under the KR Government and Surface Pollution Observation Unit of Environmental pollution Observation Administration of the Kyrgyzhydromet under the MES of the KR.
Issyk-Kul deep water monitoring across whole lake from the surface to the deepest points by different parameters under Projects support is being implemented since 2015. The physical and chemical parameters help identify water quality and general environmental status of lake.
In 2015, 26 samples were taken across all lake levels from surface till the depth, and 656 analyses by 27 indicators have been made. In 2016 and 2017 the number of samples take has been increased up to 39 and number of analyses was 1225 by 30 indicators. In June of current year sampling was performed across whole lake to the deepest sites.
The results of previous analyses have demonstrated that chemical composition and water quality of lake for the investigation period was not changed significantly in comparison with historical data set available in archive of Kyrgyzhydromet. Lake salinity is stable; oxygen regime is satisfactory; water transparency is high – about 19 meters; color is typical for marine water; and water mineralization is enough high.
