Incumbent Sharon Megdal won re-election to represent Pima County on the Central Arizona Water Conservation District.
In a five-way race for four open seats, the race was too close to call for four other candidates for the board, which governs operations of the Central Arizona Project.
With most precincts reporting in the nonpartisan race for five nonpartisan seats, Megdal was followed in order by newcomer Karen Novak-Cesare, a landscape architect, and incumbents Pat Jacobs and Warren Tenney.
Wesley Mehl, a lawyer who works as vice president and general counsel for a real-estate firm, was polling last in a race in which the top four vote-getters win election.
Pima County has four seats on the 15-member board, whose members serve six-year terms.
