A newly released study says if Asian carp reach Lake Michigan, they probably would find enough food to spread far and wide. Some experts have questioned whether there’s enough plankton in the lake to sustain the invasive carp away from shoreline areas. But the new report released Monday, Aug. 12, 2019, by University of Michigan scientists says despite a drop-off of plankton caused by exotic mussels, the voracious carp could feed on other organic material when venturing into deeper waters.

TRAVERSE CITY, Mich. (AP) — Asian carp are likely to find enough food to spread farther if they establish breeding populations in Lake Michigan, reinforcing the importance of preventing the invasive fish from gaining a foothold, scientists said in a paper released Monday. A study led by University...

A small pond of water has been discovered inside the summit crater of Hawaii's Kilauea volcano for the first time in recorded history, possibly signaling a shift to a more explosive phase of future eruptions. The United States Geological Survey says that after a week of questions about a green patch inside Kilauea's Halemaumau crater, researchers were able to confirm the presence of water on Thursday, Aug. 1, 2019.

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.

CONOWINGO, Md. (AP) — When the Conowingo Dam opened to fanfare nearly a century ago, the massive wall of concrete and steel began its job of harnessing water power in northern Maryland. It also quietly provided a side benefit: trapping sediment and silt before it could flow miles downstream and...

FLAGSTAFF, Ariz. (AP) — Ted Kennedy sums up what he sees along the river in the Grand Canyon: "It's buggy out there." That is to say, an experiment to change the flow of water from a dam near the Arizona-Utah state line appeared to boost the number of aquatic insects that fish in the Colorado River...

DENVER (AP) — In a story Aug. 15 about the Colorado River, The Associated Press, relying on information from the U.S. Bureau of Reclamation, reported erroneously when potential cutbacks could begin if a shortage is declared. A shortage could be declared in the latter part of 2019, and cutbacks...
