Kan. Stat. § 42-304
In case the channel of any natural stream shall have become so cut down, lowered, turned aside or otherwise changed from any cause as to prevent any ditch or conduit for the diversion of water from receiving the proper inflow of water to which it may be entitled, the proprietors of such ditch or conduit may, within a reasonable time after such change, extend such ditch or conduit to such stream, or along the course thereof, or may erect a dam or embankment for turning water into the same; and the right of such proprietors to take water from such stream through such ditch or conduit as so extended to the same amount and during the same period as prior to such change, shall be of the same priority as before such extension: Provided, That no such extension shall be allowed in such manner as to interfere with the operation or enjoyment of any other ditch, conduit or other works for the diversion, conveyance or storage of water.
