532 WATER LAW REVIEW Volume 8
<br />and was not applicable to Colorado.' Colorado applied the concept of
<br />maximum utilization historically to promote efficient use of water in
<br />the state. In Fellhauer v. People, the Colorado Supreme Court held
<br />vested rights acquired by appropriation coexisted with the principle of
<br />maximum utilization of water, stating "the right to water does not give
<br />the right to waste it. "' However, because the law has determined
<br />wastefulness of a use is relative to other use patterns, the legal opera-
<br />tion of "waste" under the prior appropriation doctrine gives appropria-
<br />tors a disincentive to make diversions more efficient. In the past, water
<br />claimed by an appropriator but left unused or that returned to its
<br />natural channel was lost to junior appropriators.' The concept of
<br />waste itself, however, changed when the benefit of its use is leaving it in
<br />its natural course. Objectors can no longer argue that leaving water in
<br />its course is "wasteful" or an invalid use after Golden and the modern
<br />development of Colorado's prior appropriation doctrine recognizing
<br />RICDs as a legitimate beneficial use. Until the state legislature ex-
<br />pressly defines "waste," then, the definition of the concept will con-
<br />tinue in terms of beneficial use.' And, when opponents of instream
<br />flow rights argue "waste," they will really be arguing over preferred uses
<br />among competing appropriators. As Professor Getches observed, "[i]f
<br />the city of Golden had authorized a subdivision to take the full amount
<br />of water out of the stream, no one would have objected .... " Thus, the
<br />true threat of the instream flow right is not that it is wasteful per se, but
<br />that the consumptive uses needed to sustain population growth will be
<br />subordinate to rights to nonconsumptive uses that, though junior to-
<br />day, will be senior rights in the future.
<br />IV. PUBLIC INTEREST IMPLICATIONS
<br />Instream Flows and Public Interest Considerations
<br />A major criticism of instream flow rights under Colorado's doctrine
<br />is that leaving water in its natural course is riparian and directly con-
<br />flicts with prior appropriation principles." However, as the Colorado
<br />Supreme Court noted in Colorado River Water Conservation District, the

<br />Issue 2 INSTREAM FLOWS, RECREATION, AND THE PUBLIC INTFREST 533
<br />test for an appropriation of water is fundamentally whether water is put
<br />to a beneficial use, and that a diversion may legitimately be accom-
<br />plished by controlling water within its natural course. " Colorado im-
<br />plicates public interest considerations by instream flow rights that have
<br />the effect (if not purpose) of preserving natural flows for environ-
<br />mental conservation.
<br />The Public Interest in the West
<br />In most prior appropriation states, the entity vested with the power
<br />to grant water rights - usually a court or administrative agency -is re-
<br />quired to make public interest or public welfare considerations."'
<br />Where defined by state legislatures, state courts often look to the terms
<br />of public interest statutes to determine what factors those entities
<br />should consider. For example, in Shokal v. Dunn, the Idaho Supreme
<br />Court looked to the statutory language defining instream flows to de-
<br />termine what factors the state's Director of Water Resources was to
<br />consider in rejecting or modifying a fishery's application for water
<br />rights." The Idaho court noted that public interest duties derive from
<br />the larger public trust doctrine. Thus, the court ultimately looked to
<br />the state laws defining, inter alia, instream flows and conservation to
<br />determine the elements of the local public interest. "' The court con-
<br />cluded that it was in the public interest to conserve and protect mini-
<br />mum flows necessary to protect fish and wildlife, recreation, aesthetics,
<br />and water quality.
<br />Shokal also cited the case of Young & Norton v. Hinderlider. "' In that
<br />case, the New Mexico territorial engineer denied the application for

<br />tions for instream flows.

<br />erations in a prior appropriation context, a California superior court held that even
<br />after the waters from a lake had been acquired by appropriation, "[t]he state ha[d] an
<br />affirmative duty to take the public trust into account in the planning and allocation of
<br />water resources, and to protect public trust uses whenever feasible." Nat'l Audubon
