The opinion has been voiced that in Taiwan with its limited space and dense population, the way the water resource protection zones for most existing reservoirs have been designed to stretch from the watersheds above 3000 meters all the way down to the plains means that their area is too great, and this is the cause of many of the problems.
有人認為，台灣地狹人稠，現有水庫水源保護區的設定，常由三千公呎的集水源頭開始劃設，一路至平地，面積過大，才會有許多問題。
