Section 37-82-101 - Waters of natural surface streams subject to appropriation(1) The water of every natural stream, as referred to in sections 5 and 6 of article XVI of the state constitution, includes all the water occurring within the state of Colorado which is in or tributary to a natural surface stream but does not include nontributary groundwater as that term is defined in section 37-90-103. All nontributary groundwater shall be subject to such administration and use as the general assembly may provide by law. Such nontributary waters, when released from the dominion of the user, become a part of the natural surface stream where released, subject to water rights on such stream in the order of their priority.(2) A stream system which arises as a natural surface stream and, as a natural or man-induced phenomenon, terminates within the state of Colorado through naturally occurring evaporation and transpiration of its waters, together with its underflow and tributary waters, is a natural surface stream subject to appropriation as provided in subsection (1) of this section.L. 69: R&RE, p. 1219, § 2.
