Details

The Sina, one of the large left-bank feeders of the Bhima, rises 22 km. west of Torna in Ahmadnagar district and runs south east through Ahmadnagar and Solapur district to fall into the Bhima near Kudul about 25 km. south of Solapur, on the Maharashtra and Karnataka boundary. Of its entire length of 180 km, the river has a length of 177 km within the district. About 7 km. north of Mohol, the river receives the Bhogavati river on its left bank. Another small tributary on the left bank is the Gorda nadi joining the Sina east of Madha. The Sina is about 100–200 metres broad and has steep banks. The bed is generally sandy but occasionally rocky. While upstream of Mohol, the river flows through a narrow valley, downstream it opens out widely to merge into the broad valley of Bhima. The Sina is crossed by five ferries, one in Madha at Kolgaon, and four in Solapur at Lamboti, Tirha, Vaddukbal and Vangi.^[1]
