In 1996, 50% of streamgaging stations reported above-normal flows, while 29% reported below-normal flows. Record wet years on both coasts led to high loads of sediment, nutrients, and chemicals affecting water quality and living resources.
The USGS has prioritized flood-level data to emergency-management teams, providing information on past floods, likelihood of recurrence, and flood effects. Field crews have repaired telemetry equipment, despite interrupted real-time transmission, and will study landslides to determine cause and effect.
A new USGS report explores the environmental consequences of dams, including erosion, waterfowl habitat changes, and loss of river sand bars. The report emphasizes the importance of interdisciplinary scientific approaches to minimize negative impacts and promote informed decisions about dam management.
The Yanomamo tribe, numbering around 25,000, is facing a major survival crisis due to the devastating floods in Venezuela's Amazon region. The flooding has imperiled clusters of Yanomamo living near the Orinoco River and destroyed their staple food crops, leading to increased sicknesses and potentially uncontrollable epidemics.
