Pyramid Lake is the largest natural lake entirely within the state of Nevada in the USA and covers an area of about 500 km2.
Every year around this time, Pyramid Lake is affected by a natural algal bloom, which algae is a result of the abundance of nutrients in the lake, which leads to a multiplication of algae.
In this image, acquired by one of the Copernicus Sentinel-2 satellites on 8 October 2023, the waters of the lake are coloured green, indicating an ongoing bloom.
The resolution of the Copernicus Sentinel-2 satellites (10 m in several of its spectral bands) allows to monitor water quality around the world.
