Sola beel, one of the notable wetlands of Guwahati city, is situated near Paltan Bazaar. It has been identified as a large water storage beel (lake). The beel once provided a habitat for a large number of flora and fauna and receives rainwater from nearest hills and plains. Sola beel consists of the Barsola and the Sarusola. The misfortune of this beel (the composite) started when the Revenue Department initiated the process of issuing land documents to the people who started residing on its banks. While issuing such land documents, the importance of this wetland as a storm water reservoir was not taken into consideration. Encroachment started on the lake and as a result, the size of the beel started shrinking rapidly.
