C.R.S. § 7-42-108

Every ditch corporation formed under the provisions of law shall be required to keep its ditch in good condition so that the water shall not be allowed to escape from the same to the injury of any mining claim, road, ditch, or other property. If it is necessary to convey any ditch over, across, or above any lode or mining claim or to keep the water so conveyed therefrom, the corporation, if necessary to keep the water of the ditch out or from any claim, shall flume the ditch so far as necessary to protect the claim or property from the water of said ditch.
