Geography

Lake Amtkeli is fed by the Amtkeli River, but only a small part of its water percolates through the obstructing rubble back into the river. The greater part leaves the lake through underground passages to the Jampal River. Due to the lake's limited discharge capacity, its water level rises strongly during snowmelt in May, leading to annual fluctuations of up to 40 m (131 ft) in the lake's average 512 m (1,680 ft) height above sea level and 65 m (213 ft) maximal depth, and increasing its length from 2.4 km (1.5 mi) to 4 km (2.5 mi). The average surface area of Lake Amtkeli is 0.58 km2 (0.22 sq mi), and its drainage basin measures 153 km2 (59 sq mi).

Due to the lake's origin, its underwater slopes are steep, following the surface slopes.[4]

Environment

Lake Amtkeli is home to trout, chub, nase, barbel and spirlin.

In July and August, the lake's average surface temperature is 20 °C (68 °F), in Winter it rarely freezes over.[4]

Human settlement

The village of Azanta is located next to lake Amtkeli, and some of its inhabitants keep fishing boats on its shore.[4]

gollark: Did someone purge this or is my client just being evil?
gollark: I see.
gollark: So why expect the government to actually do *sensible* things if the population is too stupid to be trusted?
