Coors Brewing Co. v. City of GoldenAnnotate this Case
This case centered on Coors Brewing Company’s application to amend its decreed augmentation plans to authorize the reuse and successive use of return flows from water that Coors diverted out of priority pursuant to those plans. The City of Golden opposed this application, arguing that Coors could not proceed by amendment but had to adjudicate a new water right to reuse or make successive use of the return flows. The water court ruled: (1) any amount of water not beneficially used by Coors for the uses specified in its decreed augmentation plans had to be returned to the stream; (2) Coors’s decreed augmentation plans did not authorize the reuse or successive use of such water; and (3) Coors could not obtain the right to reuse or make successive use of such water by way of amendment to its augmentation plans but could only obtain such rights by adjudicating a new water right. Coors appealed, arguing that the water court erred: (1) by holding that Coors could not proceed by amendment but had to adjudicate a new water right; (2) by concluding that water unconsumed by Coors’s initial use had to be returned to the stream and was subject to appropriation by other water users; and (3) interpreting Coors’s augmentation plan decrees to require permanent dedication of return flows to the stream. The Colorado Supreme Court concluded that in order to obtain the right to reuse and make successive use of the return flows at issue, Coors had to adjudicate a new water right and could not circumvent this requirement by amending its decreed augmentation plans. Furthermore, the Court held that the diversion of native, tributary water under an augmentation plan did not change its character. Accordingly, the general rule, providing that return flows belong to the stream, applied. Finally, the Court concluded the water court correctly construed Coors’s augmentation plans.
