Colorado Revised Statutes Title 31. Government Municipal § 31-35-201. Leasing of water--no rights vested

In the event any municipal appropriator of water, having a population in excess of two hundred thousand, leases, after May 12, 1931, water not needed by it for immediate use, no rights shall become vested to a continued leasing or to a continuance of the conditions concerning any return water arising therefrom so as to defeat or impair the right to terminate the leases or change the place of use. Any leasing shall not injuriously affect rights vested in other appropriators prior to said date. Nothing in this section shall authorize an appropriator to recapture water for a second use after it has once been used by it.
