Nanoconfined water (water pocket) and ionic liquid crystals (ILCs) were formed in a hydrophilic ionic liquid (IL)-D$$_{2}$$O system. Herein, 1-decyl-3-methylimidazolium nitrate ([C$$_{10}$$mim][NO$$_{3}$$]) was used as the IL. By the complementary use of small- and wide-angle X-ray and neutron scattering, a complicated phase diagram of [C$$_{10}$$mim][NO$$_{3}$$]-D$$_{2}$$O was determined. The lyotropic ILCs of [C$$_{10}$$mim][NO$$_{3}$$] containing 70-90 mol% D$$_{2}$$O appeared at room temperature. At high temperature, the lyotropic ILCs transformed into the water pocket in the nanoheterogeneous liquid.
