The San Diego County Water Authority officially celebrated it 75th year at a board meeting Thursday, while also approving a record $1.7 billion, two-year budget. On June 9, 1944, San Diego voters approved the Water Authority’s formation. Three years later, water from the Colorado River began arriving to support the growing post-war population of San Diego. “It is a pleasure to celebrate the San Diego County Water Authority’s 75th anniversary. We share a common history and a common vision for water-supply reliability that has been essential to the economic vitality and prosperity to all San Diegans.
