An Afghan local explains to advisers of the 838th Air Expeditionary Advisory Group that water levels of a canal have dropped due to a damaged spillway during a humanitarian site survey outside of Shindand Air Base, Afghanistan, March 22, 2012. The advisors’ focus is the rerouting of flood water that is causing damage to various aqueduct systems and repair of a collapsed karez, a water supply system that feeds the villagers, live stock and crops of the Moghalan-e-now and Moghalan-khona villages.
