In the crystal structure of the title compound, C8H7N3O·H2O, adjacent organic molecules are linked together into a tape along the a axis through N—H...N and N—H...O hydrogen bonds. On the other hand, water molecules are linked together to form a chain along the b axis through O—H...O hydrogen bonds. The water chains and the organic molecular tapes are further connected by intermolecular O—H...O hydrogen bonds, forming a three-dimensional network. In addition, a π–π stacking interaction between the 1,8-naphthyridine ring systems with an interplanar separation of 3.246 (1) Å and a centroid–centroid distance of 3.825 (2) Å is observed.
