Officials Debate Authority Over Dam Operations During Flood Crisis
Officials in Nakhon Nayok province briefly trialed closing the spillway gates of Khun Dan Prakan Chon Dam to ease downstream flooding after heavy rains. Water‑resource engineers challenged the move, arguing that technical gate operations should be left to experts, not politicians. The episode underscores the need for a clear division of responsibility between political leaders and engineering professionals during water crises.
The dispute began on September 27 when the Deputy Interior Minister’s field visit to Khun Dan Prakan Chon Dam produced a clip showing officials discussing a brief test closure of the dam’s spillway gates to slow water flowing into flood‑hit areas downstream. Academic experts in water‑resource engineering reacted, asking whether such a trial was appropriate. The minister responded that the discussion aimed only at temporarily alleviating hardship for residents, not at issuing a permanent closure order, and noted that staff had already opened and closed the gates according to the situation. The episode reveals a blurred line between political decision‑making and technical expertise, especially as many reservoirs hold water above normal levels and require careful discharge to balance inflow. Politicians are responsible for policy, funding, inter‑agency coordination, early warnings, evacuation preparations and assistance to those affected, whereas engineers must determine gate operations by evaluating water levels, pressure, structural integrity, inflow volumes, rainfall forecasts and downstream river capacity. When politicians stick to their duties and engineers stick to theirs, without overstepping each other’s responsibilities, the result is a crisis‑management system that truly serves the public.
