It has a volume content of 5.41 million cum with a reservoir water spread area of at FRL of . The gross storage capacity of the reservoir is 680 million cubic meters and the effective storage capacity is 621 million cubic meters (Mcm). The spillway is designed for discharge of capacity / second (and is controlled by 20 gates of size, while the maximum observed flood discharge is reported to be /second. The storage behind the dam serves as a balancing reservoir for the Kakatiya Canal and regulates flow for irrigation. The command area for irrigation is . The water quality status of the Lower Manair Reservoir was studied from September 2009 to August 2010 for the physico- chemical parameters such as water temperature, pH, turbidity, transparency, total dissolved solids, total hardness, chlorides, phosphate, nitrates, dissolved oxygen (DO) and biological oxygen demand (BOD). The results indicated that all parameters of water quality were within permissible limits and it was concluded that the water in the reservoir was fit for use for irrigation, drinking water supply and pisciculture.
