Cameron Ensor (pictured) and Nickolas Grim of the Pennsylvania Water Science Center cut through 7+ inch thick ice in order to make a discharge measurement at 01571184 Mountain Creek near Pine Grove Furnace, Pennsylvania on January 3, 2018. This gage is part of the USGS Federal Priority Streamgage Network. The temperature during their visit was -4F.

The Kafrein Dam captures runoff from Jordan River side valley wadis, near the Dead Sea, Jordan. USGS hosted a field trip that included a stop at the dam in February, 2017 during a regional workshop on aquifer storage & recovery in the Middle East and North Africa (MENA) region, in cooperation with the U.S. Agency for International Development.

Large groundwater withdrawals in the Azraq Oasis area, Jordan, have contributed to declining water levels in wells. This map shows the withdrawal footprint and observed water-level trends (labeled triangular symbols, from Goode et al. 2013).

The USGS gages the St. John River at Fort Kent, Maine at Station 01014000. A major flood in 2008 was the highest flow measured at this station, based on record going back to the 1920s. This photo shows the International Bridge in Ft. Kent, right at the water surface of the flooded river.
