Rudy Fischer, a recent transplant to the state and a former businessman, will become Arizona’s newest voice in the state’s struggle with historic uncertainty on the Colorado River.  Fischer won a place as the only new member on the Central Arizona Water Conservation District’s board of directors this year. He will replace Jennifer Martin-McLeod, who did not seek re-election. Fischer will begin his six-year term on Jan. 17, becoming one of 15 board members, including four incumbents who were returned to office.  The election adds a relative newcomer to Arizona’s water world as the state forges through interstate negotiations over strained supplies in the Colorado River. The CAWCD board, which can influence Arizona’s negotiating positions on the river, will take on the arrival of critical long-term water cuts on the river during Fischer’s term.
