The Jouganjigawa Fan, an area of rice farming of 50 km2, lies to the southeast ofToyama city and was formed in the Late Quarternary by terrestrial gravel deposi-tion by the Joganji River. To identify sources of water in shallow aquifers (maxi-mum depth 100 m) beneath the fan, studies of hydrogen and oxygen isotopes in theground and surface waters of the fan have been made. Major rivers flowing ontothe fan are from higher-altitude catchments (maximum altitude 3000 m) and havelower 6D and 6 18O values than rainfall on the fan. The isotopic measurements indi-cate that the aquifers are mainly recharged by infiltration of the irrigation water, which is derived from the Joganji River, and local precipitations from the surface.In narrow areas along the Jinzu and its tributary the Kumano Rivers, the aquifersare locally recharged from the Jinzu and Kumano Rivers, respectively. Chemicaldata support this identification of sources of water in the aquifers.
