Damanganga Basin – Rapid rise in water level in Damanganga basin in the districts of Nasik in Maharashtra, Valsad in Gujarat and Daman in UT of Daman and Diu during the next 48 hours. Since the level in Madhuban Dam in Valsad district of Gujarat is low, there will be good inflows increasing the water level and storage in the reservoir.
Krishna Basin – River Krishna and its tributaries are likely to rise in upstream districts of Satara, Sangli, Kolhapur, Pune, Sholapur districts in Maharashtra. Since most of the dams in Krishna Basin are having very low storage, the inflows into Dams in Maharashtra may increase with the forecasted rainfall.
