536 WATER LAW REVIEW Volume 8
<br />Colorado Supreme Court specifically stated a mandate by the Colorado
<br />Constitution to protect the public interest in water, which justified the
<br />General Assembly in giving the State Engineer standing to contest ad-
<br />judications." Then in 1979, the court again upheld controversial in-
<br />stream flow appropriations — challenged as unconstitutional —in Colo-
<br />rado River Water Conservation District V. Colorado Water Conservation
<br />Board. 123
<br />In 1983, the court decided the case of Alamosa La Jara," At issue
<br />was the State Engineer's interpretation of the law governing priority in
<br />the context of interstate compact agreements.` The court held that in-
<br />state users of water might have their supply curtailed in order to satisfy
<br />the essentially treated senior priority rights of out -of -state commit -
<br />ments. "' Important for public interest considerations, the court ac-
<br />knowledged the relevance of environmental factors and tempered the
<br />principle of maximum utilization by stating that
<br />the policy of maximum utilization does not require a single- minded
<br />endeavor to squeeze every drop of water from the valley's aquifers.
<br />[Statutory law] makes clear that the objective of "maximum use" ad-
<br />ministration is "optimum use" ... optimum use can only be achieved
<br />with proper regard for all significant factors, including environmental
<br />and economic concerns. 127
<br />Seemingly, in Alamosa-La Jara, the Colorado Supreme Court mimicked
<br />the method of the Idaho court in Shokat by divining public interest
<br />considerations not from any existing statutory mandates, but instead
<br />from subsequent related statutes (i.e. the WRDA granting the CWCB
<br />authority to appropriate minimum flows for conservation) and aca-
<br />demic sources.' However, unlike the status of the law in Idaho at the
<br />ruling of Shokal, no express statutory duty to consider the public inter-
<br />est in allocating water rights existed in Colorado at the time when the
<br />court decided Alamosa -La Jara, nor does any such statute currently ex-
<br />ist. Thus, it seems that the State Engineer might still administer water
<br />rights without considering public interest factors," in which case the

<br />grounds for a challenge would be failure to effect the optimum utiliza-
<br />tion of water under the maximum utilization doctrine. "'
<br />After the Alamosa-La Jam decision, the Colorado Supreme Court
<br />looked at the case of R.J.A., Incorporated v. Water Users Association of Dis-
<br />trict 6" In R.J.A., the Colorado Supreme Court denied a water right to
<br />an Estes Park summer resort business that wanted to remove peat moss
<br />from a mountain valley to free waters for appropriation.`' Though the
<br />case hinged on whether the waters sought from the peat bog were
<br />tributary and therefore subject to adjudication under the WRDA,
<br />again, as in Alamosa La,Jara, the court noted in terms of public interest
<br />concerns that
<br />[t]he water rights sought here are based upon alterations of long ex-
<br />isting physical characteristics of the land. Alteration of natural condi-
<br />tions and vegetation in order to save water carries with it the potential
<br />for adverse effects on soil and bank stabilization, soil productivity,
<br />wildlife habitat, fisheries production, water quality, watershed protec-
<br />tion and the hydrologic cycle. Whether to recognize such rights, and
<br />thus to encourage innovative ways of reducing historical consumptive
<br />uses by modifying conditions found in nature, is a question fraught
<br />with important public policy considerations. As such, the question is
<br />especially suited for resolution through the legislative process."
<br />While R.J.A. and Alamosa-La Jara are not monumental cases in
<br />themselves, they subtly demonstrate the Colorado Supreme Court's
<br />avoidance of fully implementing considerations of the public interest,
<br />though it clearly acknowledges the intention of the state legislature to
<br />protect those concerns. This is important because it explains, in part,
<br />why Colorado courts can today uphold that the state's doctrine of wa-
<br />ter rights remains that of "pure" appropriation. Whereas in most other
<br />Western prior appropriation states statutes require a court or adminis-
<br />trative agency to consider the public interest in granting water rights,
<br />in Colorado, the state legislature has not mandated these measures. As
<br />such, neither the Colorado water courts nor the state supreme court is
<br />required to adjudicate water rights in consideration of the public in-
<br />terest. Moreover, the current statutory configuration accommodates
<br />this avoidance of the public interest in the courts. As noted above,
<br />principles of the public interest appear by statute only in reference to
<br />minimum instream flows that the CWCB may appropriate and recom-
<br />mend for RICDs sought by local government entities. Even these pro-
<br />visions are not mandates, though, and since the function of the CWCB
