Nearly 300 residents of over 10 societies near Charkop lake, a 50-year-old water body, fear that construction on the lake is going to adversely affect them in the coming monsoon. In February, the residents had raised a red flag over partial filling of the six-acre lake for a housing project. Consequently, on February 20, the Mumbai Suburban Collector's office issued a notice to stop the land-filling till further notice and ordered a high-level inquiry into the issue.
