Any board or group of boards or local unit or units acting singly or in concert may request the department to undertake a survey of the water in a river basin or watershed located or partially located in the county or counties or in the local unit or units of government to determine whether there is surplus water that may be available and, if so, how it may be best impounded, utilized, and conserved. All studies, surveys, and reports made by public and other competent authorities may be utilized by the department in making this determination.
