Lower Manair Dam

Lower Manair Dam also known as LMD was constructed across the Manair River, at Alugunur village, Thimmapur mandal, Karimnagar District, in the Indian state of Telangana during 1974 to 1985. It provides irrigation to a gross command area of .
Location.
The Lower Manair Dam is located on the Manair River at 18°24' N latitude and 79° 20' E longitude in Karimnagar District at Km.146 of Kakatiya Canal. The Manair River is a tributary of the Godavari River and the dam is built across the river at the confluence with Mohedamada River. The dam drains a catchment area of which includes of free catchment and the balance is intercepted catchment. Karimanagar town is away from the dam.
In the vicinity of the LMD which is the only place of recreation for the people of Karimnagar, in the light of recent drowning incidents and the insecurity created by hooligans, security measures have been stepped up.
Features.
Lower Manair Dam's construction was started in 1974 and commissioned in 1985. It is an Earth cum Masonry dam. The dam height above the deepest foundation is ; the maximum height of the earth dam is . The dam length is , top width is . It has a volume content of 5.41 million cum with a reservoir water spread area of at FRL of 920.00 ft. The gross storage capacity of the reservoir is 680 million cubic meter and the live storage capacity is 380.977 million cum. 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.
Reservoir fisheries.
Studies were conducted in the LMD reservoir from June, 2013 to May, 2014 to identify the larvivorous activity of fishes. On the basis of morphometric and meristematic characters, the 58 fish species are identified in the reservoir. Also reported were 53 ornamental fish species comprising eight orders; of these 23 species belong to cypriniformes order. "Awaous grammepomus", also called Scribbled goby was also identified.
