The title compound, C16H11ClN2O2·H2O, exists in an E conformation with respect to the N=C bond. The benzofuran ring system forms a dihedral angle of 1.26 (4)° with the benzene ring. In the crystal, mol­ecules are linked via (N,C)—H⋯O bifurcated acceptor hydrogen bonds and (O,O,C)—H⋯O trifurcated acceptor hydrogen bonds, forming layers parallel to the bc plane.
