The legislative assembly finds that the use of ground water for irrigation purposes is vitally important to the economic future of this state. The reliance on processing plants for the consistent quality resulting from irrigation is an important factor in preserving this state’s reputation for quality agricultural production. Therefore, it is declared necessary and in the public interest that the state by and through the state water commission strongly discourages the conversion of agricultural water permits to any other use. Further, the legislative assembly declares that any feasible or reasonable alternative supply of water be made available for municipal or domestic use to enable the continued use of ground water for irrigated agriculture and agricultural processing.
