Record-Breaking Flooding in Australia (Image of the Week)

In May 2025, record rainfall in Australia's New South Wales created major flooding along the coast. In Taree, a mid-North Coast city, the Manning River reached a height of 6.4m on May 21st. The previous record of six meters was set back in 1929. The torrential rains have left almost 800 properties and counting uninhabitable in New South Wales.

The world’s largest iceberg floats freely in the Southern Ocean.

Iceberg A23a is a 1,500 square mile ice mass larger than the state of Rhode Island. A23a weighs approximately 1 trillion tons and measures around 1,300 feet thick.

Landsat satellites capture images of the Earth’s surface. While the sensors aboard Landsat capture a wide range of scientifically useful wavelengths, this collection reveals natural color imagery in the red, green and blue parts of the visible spectrum, as if viewed by the naked eye from 438 miles above the surface.

The 3D Hydrography Program (3DHP) database will initially be populated with the National Hydrography Dataset (NHD) features, mapped to the new data model. The NHD-source features will be replaced with hydrography derived from the 3D Elevation Program (3DEP) lidar and IfSAR data as it becomes available.

A large, round lake in Quebec, Canada, highlights the geography of an ancient impact crater.

In the late Triassic Period, a 3 mile wide meteorite struck northern Pangea at over 30,000 miles per hour.

The resulting crater is now 214 million years old, but the dramatic circular lake visible in 2024 Landsat imagery is a surprisingly recent feature.

Federal Fiscal Year 2024 was the first full operational year for the 3D Hydrography Program. We made significant progress in a number of areas, publishing final versions of legacy products, and developing processes for the new program. This presentation will provide an overview of what was accomplished in FY24 and what is planned for FY25.

The Klamath River, flowing from the high desert interior of Oregon and through the redwood forests of California, once produced large runs of salmon and trout. However, the construction of hydroelectric dams, beginning in 1918, blocked fish migration, encroached on Indigenous culture, and impacted water quality.
