S-2-22497M/KK/79 ABSTRACT OF THE DISCLOSURE This invention discloses an inflatable flexible envelope type dam including members having a large specific gravity attached to said envelope. The members allow said envelope to fall down in its deflating state by overcoming the buoyancy given by residual fluid in the envelope. This then provides an improved device over the prior art types by providing an improved inflatable envelope type dam capable of preventing floating during its deflated state.
