Some two decades later, the Medina River Adjudication, 670 S.W.2d 250 (Tex. 1989) presented the Texas courts with the ultimate question as to Spanish and Mexican water law in Texas: Did the ownership of a Mexican-era surface grant encompassing a section of traversing nonperennial waters carry with it irrigation rights in and to these waters? Such rights could exist, if at all, only by operation or implication of law, since the classification of the grant there in-volved as grazing land with a few lahores fit for dry farming directly contradicted any implied factual intent to grant irrigation rights.
