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.

View south-southwest across maar crater of Gura 1 toward benmoreite lava dome and flow of Um Junb. Trachytic pyroclastic flow deposits of Gura 2 enter from upper right, mantling mugearite lava flow of Dabaa 1. Maar crater is about 0.7 kilometers across, and Um Junb stands about 250 meters above surroundings.

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).
