A fixable-seal sluice gate has a valve vise that forces a sluice-gate valve uniformly and tightly in sealing-surface contact with a domed seal ring that is fixable conveniently and removably intermediate a sluice-gate plate and a sluice-gate wall of a sluice-gate flange that encompasses a valve side of a sluice-gate aperture. A plate locator on the valve vice sets the sluice-gate plate in predetermined sealing- contact position for select structure of the fixable-seal sluice gate. The domed seal ring is a plastic material such as Hypalon® having predetermined toughness to resist particle embedment in combination with having predetermined softness for select uses and objectives. A dome flange on one or both sides of a base of the domed seal ring is bracketed removably to optionally the sluice-gate wall or the sluice-gate plate for rigid, reliable, long-enduring and yet quick and convenient attachment and detachment of the domed seal ring.
