C.R.S. § 38-2-103: Proceedings to drain.

Whenever the owners of any parcels of land desire to construct a drain for the purpose of carrying off surplus water and they cannot agree among themselves or with the parties who own land below, through which it is expedient to carry the drain in order to reach a natural waterway, then proceedings may be had in the same manner as in cases of eminent domain affecting irrigation works of diversion. The rights-of-way for such drains shall be regarded as equal to those for irrigation canals.
