In the year 1964 Wheatland Irrigation District, pursuant to Â§ 41-48, W.S. 1957, and as a junior appropriator and contestant, commenced two proceedings before the State Board of Control, seeking a declaration of partial abandonment of certain adjudicated direct-flow and storage water rights owned by Pioneer Canal Co. By agreement of the parties and the board, the two proceedings were consolidated for hearing; were to be heard by the board; and came on to be heard on August 15, 16, and 17, 1966, and on November 14 and 15, 1966. Thereafter the board entered separate orders denying the relief sought. The contestant thereupon, in March and July 1967, filed its petitions in the District Court of Albany County, Wyoming, requesting the court to hold a hearing de novo on the decisions rendered by the board as provided in Â§ 41-53, W.S. 1957; and after certain preliminary procedural matters were presented to the court, about which more will be said, the court entered its order affirming in all respects the orders entered by the board. This appeal followed. For convenience and better understanding we will separately discuss the matters pertaining to each of the proceedings before the board and the contentions of the parties with respect thereto.
