But a corresponding management system, for example, a mechanism for officially announcing when water levels are safe, when they merit a warning and when there is a serious drop in water levels, as well as setting up measures to respond to these things-all this waits to be worked on.
但相關的管理制度，例如隨時公佈安全水位、警戒水位、嚴重下陷水位的機制，以及建立各種因應措施等，都還有待努力。
