Pune’s civic and irrigation authorities issued an alert for residents living along the Mutha River after the Khadakwasla dam, the city’s primary water source, filled at an unusually fast pace this week. The reservoir climbed from about 62% of capacity early Tuesday to roughly 94% by Tuesday evening, and officials began a controlled release of water into the Mutha from midnight as a precaution, according to Free Press Journal and Punekar News.
An initial discharge of 800 cusecs was ordered, with the Pune Irrigation Circle warning that the rate could be stepped up sharply, to between 5,000 and 8,000 cusecs, if inflows kept climbing overnight. Pravin Kolhe, Superintending Engineer of the Pune Irrigation Circle, said the department would continuously track inflow, catchment rainfall and weather conditions before adjusting the release further.
Why the dam filled so fast
Khadakwasla, along with Pune’s other three main reservoirs, had a relatively slow start to this year’s monsoon, mirroring the delayed statewide onset reported here in June. But a run of intense rain through the first week of July reversed that quickly: the dam’s live storage jumped from around 3 TMC to nearly 7 TMC in a matter of days, taking it to the edge of its roughly 2 TMC capacity. That kind of swing is exactly the scenario dam managers dread — a reservoir that goes from comfortably low to spilling within 24-48 hours leaves little room to stagger releases gently.
What it means for residents
For people living or working along the Mutha’s banks — including stretches near Deccan, Kothrud, Erandwane and Vitthalwadi — a controlled release still means a real rise in river levels, and civic officials have asked residents to move vehicles, livestock and belongings out of the riverbed as a precaution. The bigger risk isn’t the planned 800-cusec release itself but what happens if the dam tops out and authorities are forced into a sudden, much larger spillway discharge with less notice. Pune has been through this before: sharp releases from Khadakwasla and neighbouring dams have caused flash flooding along the Mutha in past monsoons, which is why irrigation officials are trying to manage the outflow in stages rather than waiting for the reservoir to overflow on its own.
The timing compounds an already difficult week for road and traffic infrastructure in the district — the Mumbai-Pune Expressway’s “missing link” near Tunnel 2 was shut for over 18 hours after a landslide before reopening Tuesday, and the old Mumbai-Pune highway also saw a temporary closure after a tree fell across the carriageway.
What to watch
The key numbers to track over the coming days are Khadakwasla’s storage percentage and the release rate from the spillway, both of which the Pune Irrigation Circle updates as rainfall in the Sahyadri catchment evolves. If the current spell of heavy rain continues, residents downstream should expect further, possibly larger, releases with short notice — a pattern that has become more common as Pune’s monsoon swings between deficit and sudden excess in recent years.
