乔治湖(英语:Lake George),一个位于澳大利亚新南威尔士内流时令湖。乔治湖位于堪培拉的北边。

地理

[编辑]

乔治湖是一个内流湖,不过它没有河流或是冰川供水,所以乔治湖的水到底从何而来目前还没有人知道。 大约一百万年前,溪流从乔治湖流入亚斯河英语Yass River。后来,乔治湖的湖岸抬升,使得溪流被切断,乔治湖成为了内流湖。[1]

乔治湖最大深度为1.5-4.5米,但是大多数湖区只有0.8-1.0深,最深点为7.5米。乔治湖可以装下500,000,000立方米(1.8×1010立方英尺)的水。

水位变化

[编辑]

乔治湖著名于它的水位变化。平均每过大约40年湖泊就会经过一个周期:其中20年湖泊干涸,另外20年湖泊充满水。在干旱时期,乔治湖盆是一片牧场,种植着葡萄也在那里吃草。

而从2021年底起,该湖泊再度蓄水。

(原始内容 (pdf (see pages 9 - 10))存档于2007-08-31). Lake George, one of the world's oldest lakes, is shallow and has a history of dramatically fluctuating water levels, despite being closed with no outlet. Originally there was no lake at all, and water drained from the Great Dividing Range west to the Yass River. That was before geological uplift, five million years ago, which formed the Lake George Range — a natural dam blocking the creeks.
