Summary

[edit]
Description
English: An astronaut onboard the International Space Station (ISS) captured this downward-looking (nadir) photograph of the Amistad Reservoir, which is on the border of Mexico and Texas. The reservoir is located just west of the city of Del Rio. It was created in 1969 with the completion of the Amistad Dam, built at the confluence of the Rio Grande and Devils River in order to store water and prevent local flooding.

The lake and river levels regularly fluctuate due to rainfall or drought. When water depth is at the conservation pool level, Amistad is the second largest lake in Texas. However, the last time the reservoir hit conservation pool level was in 2011. The area is currently abnormally dry (according to the U.S. Drought Monitor), and the reservoir level is 32 feet below the 2011 level (data as of June 4, 2019.)

The U.S. portion of the reservoir and surrounding land is known as the Amistad National Recreation Area, and it is home to a unique combination of flora and fauna. There are three major plant communities in the area—Tamaulipan Shrubland, Chihuahuan Desert, and Edwards Plateau—as well as two major climate zones (temperate and tropical), making for significant biodiversity in the park. The area is also a waypoint for seasonal migrations of animals and insects, with the most significant being Monarch butterflies. Thousands of Monarchs pass through the area each October on their way to the mountains of central Mexico.
Deutsch: Ein Astronaut an Bord der Internationalen Raumstation (ISS) nahm diese nach unten gerichtete Photographie des Amistad Reservoir auf, das sich an der Grenze zwischen Mexiko und Texas befindet. Der Stausee liegt direktwestlich der Stadt Del Rio. Er entstand 1969 mit der Fertigstellung des Amistad Dam, der am Zusammenfluß von Rio Grande und Devils River errichtet wure, um Wasser zu speichern und lokale Überschwemmungen zu verhindern.

Das Niveau des Sees der des Flusses schwankt regelmäßig wegen Nieerschlägen und Trockenperioden. Wenn der Wasserstand das Schutzstauziel erreicht, ist das Amistad Reservoir der zweitgrößte See in Texas. Allerings wurde dieser Stand zuletzt 2011 erreicht. Das Gebiet ist derzeit (Juni 2019) nach den Angaben des U.S. Drought Monitor abnormal trocken, und der Wasserspiegel des Sees lag am 4. Juni 2019 rund 32 Fuß (9,6 m) unterhalb des Standes von 2011.

Der in den Vereinigten Staaten liegende Teil des Stausees und das umgebende Gelände bildet die Amistad National Recreation Area, die Heimat einer einzigartigen Kombination von Flora und Fauna. In dem Gebiet sind drei Pflanzengesellschaften vorherrschend – Tamaulipan Shrubland, Chihuahuan Desert und Edwards Plateau – und zwei Hauptklimazonen (gemäßigt und tropisch), was für eine signifikant hohe Biodiversität in dem Park sorgt. Das Gebiet ist auch ein Ruheplatz für die saisonalen Wanserungen von Wirbeltieren und Insekten, vor allem von Monarchfaltern. Tausende von Monarchfaltern ziehen jeden Oktober auf ihrem Weg zu den Bergen in Zentralmexiko durch das Gebiet.
