" Mauryan empire towards the satrapies of Gedrosia part of which were ceded by Seleucus to Chandragupta. The discovery of the remains of a large Buddhist sanctuary on "Koh-i-Khwaja" in Sistan suggests that this province also was perhaps included in the Mauryan empire, and the Buddhist influence reached there in the time of Asoka himself."
Further south, that Jaz Morian Lake have marked this side the western boundary of the Mauryan empire. As the name suggests, this place commemorates some signal victory or achievement of the Mauryan emperors. It may be the construction of the lake itself like the big Sudarsana lake by Chandragupta further east in Kathiawad"
