Colo. Rev. Stat. § 37-80.5-102
The general assembly hereby finds, determines, and declares that the purpose of this article is to authorize the creation of water banks within each water division to be operated under strict parameters established by rules approved by the water court. Accordingly, this article provides for the promulgation of rules concerning water banks and requires the water court to approve the rules and the state engineer to report to the general assembly regarding the operation of the banks. The water bank program created by this article is intended to simplify and improve the approval of water leases, loans, and exchanges, including interruptible supply agreements, of stored water within each river basin, reduce the costs associated with such transactions, and increase the availability of water-related information. It is also the purpose of the water banks to assist farmers and ranchers by developing a mechanism to realize the value of their water rights assets without forcing the permanent severance of those water rights from the land. The general assembly affirms the state constitution's recognition of water rights as a private usufructuary property right, and this article is not intended to restrict the ability of the holder of a water right to sell, lease, or exchange that water right in any other manner that is currently permitted under Colorado law. Further, this article is not intended to be implemented in any way that would cause material injury to the owner of or persons entitled to use water under a vested water right or a decreed conditional water right, nor to repeal or in any manner amend the existing water rights adjudication system except as may be specifically set forth in this article.
