Wyo. Stat. § 41-7-203: Land that may be included in proposed district.

The lands proposed to be included in any irrigation district, need not be contiguous provided that the benefit of the proposed work in each part will exceed the damages from costs of said proposed work in each part; and provided further that the court shall be satisfied that said proposed work can be more cheaply done if in a single district than otherwise; and provided further that lands within a town or city may be included within the limits of any irrigation district, if the creation of such irrigation district will benefit such town or city in any amount equal to or in excess of the amount of assessment for construction against the lands therein.
