Diurnal Changes of Some Physicochemical Characteristics in Reservoir Thodga, Ahmedpur, Distt. Latur, Maharashtra

摘要

Thodga dam is a medium reservoir with 165.00 ha water spread area. The reservoir is constructed on Lendi river, one of the tributaries of Manjara river system. The reservoir is on Ahmedpur-Thodga road 5 km away from Ahmedpur and 0.5 km from Thodga village. Fishermen's Co-operative society uses this reservoir for fisheries activities. The water of this reservoir is also used for irrigation and drinking purposes. Diurnal changes in temperature, pH, dissolved oxygen and carbon dioxide were estimated from 6 a.m. to 6 a.m. for 24 hours in the month of November 2002 and discussed in the paper. All the parameters have shown distinct variation in the diurnal cycle.
