With the fourth lake that supplies water to the city overflowing on Tuesday, it seems Mumbai's water woes won't be that critical the coming year. After three lakes reached 71.48 per cent of their full storage capacity of 14.47 lakh litres in the past three days, continuous rainfall over the weekend led Tansa to overflow on Tuesday morning. While Tulsi started to overflow on July 9, Modak Sagar reached its full capacity on Sunday and Vihar on Monday.
