Kawakami Dam is under construction at the Maefukase-gawa River, a subsidiary stream on the left of the Kizu-gawa River, while Yodogawa River System Committee's recommendations in 2005 led to the conclusion that "it is appropriate to abort the construction," and the agency's supervisory Ministry of Land, Infrastructure, Transport and Tourism intends to change the dam to a flood-control dam, but Mie Prefecture, Iga City, residents in the river area, and those residents to move out oppose the Ministry's intention saying that the construction should be continued as it is planned.
尚、木津川の左支川・前深瀬川には現在川上ダムが建設中であるが、2005年（平成17年）の「淀川水系流域審議会」の答申により『建設中止が妥当』という判断が下され、機構を所管する国土交通省は治水ダムへの変更を図ろうとしているが、三重県や伊賀市、流域住民や移転住民から計画通りの建設を行うべきと反発を受けている。
