The flood to other major reservoirs in Krishna basin - Srisailam, Nagarjuna Sagar and Pulichintala - remained steady and is expected to remain so as the projects in the upper catchment areas of the river in neighbouring States continue to discharge water.

At 7 pm, Prakasam Barrage recorded an inflow of 5.42 lakh cusecs. The officials were diverting about 3,000 cusecs using delta canals and the remaining 5.38 lakh cusecs of surplus was being let downstream.

Though the district officials estimated that the barrage would get about  9 lakh cusecs, the trend continued to fall. The Krishna district administration, however, continued to be on alert as the low-lying areas still remain waterlogged and the first flood warning was still in effect.

The first warning will be withdrawn when the outflow falls below the 3.96 lakh cusecs-mark.Pulichintala Project, at 7 pm, was getting 5.62 lakh cusecs and its outflow was also 5.62 lakh. Against its full reservoir level (FRL) of 45.77 TMC, the project has 41.98 TMC of water with a flood cushion of 3.79 TMC. 

Srisailam reservoir continued to receive a steady inflow. At 6 pm, the reservoir, which has 212.77 TMC of water at 884.51 feet, recorded an inflow and an outflow of 5.98 lakh cusecs. Its FRL is 215.81 TMC at 885 feet. Nagarjuna Sagar also received 5 to 5.7 lakh cusecs of water and discharged most of it downstream. It had a flood cushion of 2.69 TMC of water against its FRL of 312.05 TMC.

The flood to Gotta Barrage on Vamsadhara river reduced to 27,000 cusecs and the outflow stood at 28,000 cusecs at 4 pm. In Godavari basin, Sir Arthur Cotton Barrage in Dowleswaram recorded an inflow and outflow of 2.72 lakh cusecs at 6 pm.
