For the uses stated in this chapter, upper users have first priority for domestic use except that it is unlawful for an upper owner to build new works that would deprive a lower owner of water which has been regularly approved under this chapter. Any contest between upper and lower dry-draw owners shall be brought to the Water Management Board first for resolution. The board's ruling may be appealed to circuit court under the provisions of chapter 1-26.
