<br />upper limit to the right of private landowners to
<br />withdraw groundwater, Given public ownership
<br />of the groundwater, the legislature retains the
<br />power to define what shall constitute reasonable
<br />and beneficial use, Absent legislative directive, it
<br />seems likely that any use of water on the over'
<br />lying land suitable to the character ofthe land
<br />would be deemed reasonable and beneficial as
<br />long as the water was not wasted42 or used for

<br />ment among the overlying owners.
<br />
<br />Although apportionment has never been
<br />accomplished judicially in Nebraska, repeated
<br />case references to "sharing in time of shortage"
<br />leave little doubt that this element of the
<br />California Rule has been incorporated into
<br />Nebraska case law, Precisely how such water
<br />would be apportioned or when a shortage is
<br />"triggered" have never been established by
<br />decision, Presumably a "shortage" may exist to
<br />activate the correlative rights apportionment
<br />whenever an aquifer is depleted below its long
<br />run sustainable yield level, in other words, when-
<br />ever an aquifer is mined, As to the apportionment
<br />itself, a variety of possibilities exist. An attempt
<br />could be made to hydrologically estimate the
<br />relative proportion of the aquifer that underlies a
<br />particular tract of overlying land and to apportion
<br />accordingly, Another alternative would be to
<br />establish a uniform allocation per acre of surface
<br />area or overlying lands, A third possibility would
<br />be to apportion water based on the character of
<br />the overlying land, for instance, apportioning the
<br />bulk of the allocated water to overlying irrigable
<br />land in rural areas, It is unclear, however, whether
<br />apportionment would limit use of water to the
<br />apportioned quantity or whether apportionment
<br />would merely entitle injured parties to com pen,
<br />sation from others for excessive use,

<br />able and beneficial uses of overlying
<br />owners may, with public consent, be
<br />transferred away from the overlying
<br />lands without any oyerlying landowners
<br />suffering a compensable injury.
<br />
<br />Although this rule has never been explicitly
<br />stated by the Nebraska Supreme Court it does
<br />seem to be the clear implication of the Metro'
<br />
<br />poliran Utilities case and it is consistent with
<br />public ownership of groundwater and with the
<br />California Rule of correlative rights,
<br />
<br />5. Among members of the same preference
<br />class, overlying owners have no right to
<br />maintenance of a particular water table
<br />or artesian head.
<br />
<br />This rule was announced In Prather, An
<br />exception to the rule might occur in the event of
<br />an apportionment if the apportionment con-
<br />templated maintenance of a long run static water
<br />table,
<br />
<br />6. Among members of different preference
<br />classes, preferred users are protected
<br />from unreasonable reductions in the
<br />water table or unreasonable reductions
<br />in artesian head caused by the actions
<br />of less-preferred users.
<br />
<br />This rule also follows from Prather, It is not clear
<br />whether all subsequent interferences with prior
<br />preferred uses are unreasonable or whether a
<br />more sophisticated balancing of the equities of
<br />competing users will be used, Furthermore, it is
<br />not clear whether or not a subsequent preferred
<br />user can enforce a right to a water level or
<br />artesian head against a prior less preferred user,
<br />It seems likely, however, that a preferred user
<br />must have a current use interfered with by a
<br />subsequent non'preferred use to recover
<br />damages,
<br />
<br />7. Subirrigation of crops is a reasonable
<br />and beneficial use of groundwater.
<br />
<br />This is one implication of luchsinger, It may,
<br />nevertheless, generally prove impossible to
<br />maintain water levels required for subirrigation
<br />since presumably subirrigation and surface irri,
<br />gation would fall with the same preference class,
<br />
<br />Consequently, under Prather, a landowner
<br />would have no right to maintenance of water
<br />levels for subirrigation purposes against a
<br />pump irrigator responsible for a decline in
<br />the water tabte,
<br />
<br />Additional uncertainties exist under the series
<br />of cases set forth above, These uncertainties and
<br />questions are discussed in the next chapter,
<br />which briefly discusses the limitations inherent
<br />in the presently existing set of property rights, at
<br />least as articulated above,
