USGS scientists measuring streamflow on Rapid Creek above Canyon Lake and collecting water-quality samples in May 2017.

The upper part of the Tuul River Basin in Mongolia contains pristine water originating mostly from snowmelt. More information on this study is available at https://doi.org/10.3133/ofr20161096.

Many flowing wells have been abandoned in the Ararat Valley in Armenia. Abandoned wells create environmental hazards (such as pathways for contamination from the land surface to reach the aquifer if well casing deteriorates in nonflowing wells) and continued depletion of the artesian aquifer from flowing wells.

The growth of aquaculture to raise trout, sturgeon and other cold-water fish has increased withdrawals of critical groundwater in the Ararat Basin of Armenia. The USGS is working with partners, including USAID, to develop scientific tools for water-resource managers to understand and predict consequences of management decisions in Armenia.

Mark Anderson, Director of the USGS South Dakota Water Science Center, demonstrates how to collect a stable isotope sample from a flowing well near Sis, Armenia.

Field training on how to measure water level using a pressure gage for a flowing well in Sis, Armenia.

Training on well inventory and collection of water-level data was provided by USGS on March 1, 2016, in Yerevan, Armenia.

Field training provided by the U.S. Geological Survey on measuring the discharge from a non-flowing well near Artashat, Armenia, that is used for irrigation purposes in the summer. More information about this study is available in https://doi.org/10.3133/sir20175163.
