Exploring Earth From Space: Lake Trasimeno – The Fourth Largest Lake in Italy

Dark-colored waters in the southern part of the lake suggest an existence of submerged and drifting macrophytes (water plants) as well as algae. Lake Trasimeno, likewise referred to as Trasimene or Thrasimene in English, is a lake in the province of Perugia, in the Umbria region of Italy on the border with Tuscany. Dark-colored waters in the southern part of the lake indicate the presence of immersed and drifting macrophytes (aquatic plants) as well as algae.
Several other smaller sized lakes including Lake Montepulciano, Lake Chiusi, and Lake Pietrafitta, can be seen south of Lake Trasimeno.

Lake Trasimeno, also referred to as Trasimene or Thrasimene in English, is a lake in the province of Perugia, in the Umbria region of Italy on the border with Tuscany. The lake is south of the river Po and north of the close-by river Tiber. Trasimeno is shallow, muddy, and rich in fish, including tench, carp, and pike.

In this Copernicus Sentinel-2 image, captured on August 6, 2022, the lakes emerald green color is likely due to the existence of phytoplankton. Dark-colored waters in the southern part of the lake show a presence of immersed and drifting macrophytes (marine plants) as well as algae.
Lake Trasimeno, the fourth largest lake in Italy, is included in this weeks European Space Agency (ESA) Earth From Space image.
Lake Trasimeno lies in main Italy, around 20 km (12 miles) west of Perugia, and incorporates an area of around 128 sq km (50 square miles). It is shallow, only reaching an optimum depth of around 6 meters (20 feet), although the lakes water level varies depending upon meteorological and climatic conditions.

In this Copernicus Sentinel-2 satellite image, captured on August 6, 2022, the lakes emerald green color is most likely due to the presence of phytoplankton. Streaks in the water, particularly noticeable in the west, suggest the presence of soil and sediments that have been stimulated by strong winds. Dark-colored waters in the southern part of the lake suggest the existence of submerged and drifting macrophytes (marine plants) as well as algae.
Surrounded by hills on 3 sides, Trasimeno goes through heavy storms produced by winds, specifically from the north and west. There are 3 islets in the lake: Maggiore, Minore, and Polvese (the biggest). The lakes shores are sparsely inhabited with just two popular towns: Castiglione del Lago and Passignano sul Trasimeno.
Italy is experiencing its worst drought in 70 years which has affected drinking water materials, hydroelectric power, and agricultural production. Heats, hot winds, and absence of rainfall are the primary causes of dry spell in the Umbrian region which saw Lake Trasimeno drop 1.3 m (4.2 feet), reaching the limitation of the hydrometric absolutely no in July 2022.

Lake Trasimeno wasnt the only Italian water body impacted by drought this summer season, with the Po River hitting record lows. The Copernicus Sentinel-2 satellites record high-resolution images that provides information about the conditions in the world, such as water quality, plant life, and coastal locations.
The mountainous terrain of the Umbrian Apennine Mountains surrounds Lake Trasimeno with many farming fields dotted around the area. Several other smaller lakes including Lake Montepulciano, Lake Chiusi, and Lake Pietrafitta, can be seen south of Lake Trasimeno. Perugia, capital of the Umbria region, is a widely known cultural and creative center in Italy understood for its chocolate and jazz festivals.
