surface or subsurface or both; confined or unconfined;(31) "gpd" means gallons of water per day;(32) "gpm" means gallons of water per minute;(33) "non-consumptive water use" means the instream use of water, or the diversion of water where the quantity of water diverted is not diminished except by evaporation or transpiration and the water is returned to its original source at the original point of diversion immediately after its use;(34) "reasonably acquire" means that a permittee or certificate holder can acquire adequate water to fulfill the purposes of the appropriation from the source of water for which the water right is permitted or certificated, even though changes in the condition of water occurrence have taken place as a result of the withdrawal of water by later appropriators;(35) "seawater" means water, taken from the sea or ocean, with a salinity of 35 parts per thousand or greater;(36) "statement of beneficial use" means a notarized statement of the actual quantity of water being used from a permitted source of water for a specific purpose;(37) "water source" means a water body, lake, stream, aquifer, or ice;(38) "unduly affected" means that a prior appropriator loses the ability to reasonably acquire an adequate quantity of water to fulfill the purposes of the appropriation from the water source from which the water right is permitted or certificated, except that a prior appropriator has not been unduly affected if water can reasonably be obtained by installing more efficient diversion works for the withdrawal of water or by performing effective routine repair and maintenance of diversion works or water well equipment in order to allow for the full development of the water resource.Eff. 2/8/67, Register 23;
