There are eight major ponds at CoCC as shown in Figure 2-3. They are Ranir dighi1, Mandir dighi, Nanuar dighi, Fauzdari dighi, Modina dighi, Dargabari dighi, Darma Sagar and Thakurpara. Dharmasagar is a large pond located in Comilla town with an area of 9.38 hectares. Maharaj Dharmamanikya of Tripura (1714–1732) dug this pond to make water available to the local people. Some of its historical marks made this dighi an attractive tourist spot. Migratory birds usually visit the spot during winter. The Gomti River and the ponds are the main sources of water for the CC.
