Center issues Stop Work order for Polavaram Project Coffer Dam. Though govt announced it as a National project, not providing funds to it's completion. But AP Irrigation officers are worried about the possibility of construction of main dam without completing Coffer Dam. Govt told to send National Hydro Power Corporation experts committee in 3rd week of this month to decide over the need of Coffer Dam and to stop work until then. AP Irrigation department officials say that a project is incomplete without Coffer dam as it protects the main project. Minister Devineni Uma is hopefully expecting positive response from the govt.
