Dams

In this Wednesday, Dec. 4, 2019, photo, sightseers plays on a sandbar in the Mekong River in Nakhon Phanom province, northeastern Thailand. Experts say the aquamarine color the Mekong River has recently acquired may beguile tourists but it also indicates a problem caused by upstream dams. The water usually is a yellowish-brown shade due to the sediment it normally carries downstream. But lately it has been running clear, taking on a blue-green hue that is a reflection of the sky. The water levels have also become unusually low, exposing sandbanks in the middle of the river. (AP Photo/Chessadaporn Buasai)

Water flows through Conowingo Dam, a hydroelectric dam spanning the lower Susquehanna River near Conowingo, Md., on Thursday, May 16, 2019. Officials once counted on the dam to block large amounts of sediment in the Susquehanna from reaching Chesapeake Bay, the nation's largest estuary, but the reservoir behind the dam has filled with sediment far sooner than expected.
