EL CENTRO, Calif. (KYMA) - The Imperial Irrigation District (IID) says Merlon Kidwell, their Watermaster for 50 years, has retired. Joining IID in 1975, Kidwell ensured "the reliable delivery of water to nearly half a million acres of some of the nation's most productive farmland, as well as to cities, businesses, and industries in California's Imperial Valley," IID said. "If the water is in the banks when you get to work, then a smart Watermaster will take that as a win. "We are amazed at the expertise this requires, which is exemplified by such dedicated and respected employees as Mr. Kidwell. We truly thank him for all that he has done over the years and remain in a debt of gratitude."
