Geography

The Lower Lake is located to the east of the Upper Lake. An earthen dam separates the two lakes. The two lakes are built in a terraced manner, the lowest level of the Upper Lake is just below the highest level of the Lower Lake.

The Lower Lake has an area (water spread) of 1.29 , and its catchment area is 9.6 km2. The lake receives subsurface seepage from the Upper Lake. In the 1850s, the maximum and minimum depths of the lake were 11.7 m and 6.16 m respectively.{{cite web | url = http://bhopal.nic.in/interest.htm#Bk9 | title = Places of Interest in Bhopal | publisher = Collectorate, Bhopal | accessdate = 2011-10-28 }} As of 2011, the maximum depth was 10.7m.

The Lower Lake does not have any fresh water source; it receives seepage water from the Upper Lake and drainage from 28 sewage-filled nullahs.{{cite book | author = Prashant S.

Pollution

The Lower Lake suffers from pollution due to drainage from sewage-filled nullahs, lack of fresh water source and commercial washing of clothes. The entire lake is eutrophic, and its water is not suitable for drinking.
