“…If water is not used beneficially, the right may lapse under the doctrine of abandonment. The driest westem states, Arizona, Colorado, Idaho, Montana, New Mexico, Utah and Wyoming, recognize only appropriative water rights, whereas the wetter states of Califomia, the Dakotas, Kansas, Nebraska, Oklahoma, Oregon, Texas and Washington recognize both riparian and appropriative institutions (Kanazawa, 1998). Riparian rights grant water to adjacent land owners for reasonable use and riparian rights generally cannot be separated from the land.…”
