Atlanta Mayor Kasim Reed said Saturday that he has let go Atlanta Watershed Commissioner Jo Ann Macrina.

William Johnson, the city’s deputy chief operating officer, will be the interim commissioner, Reed said in a media release.

“I would like to thank JoAnn Macrina for her work on behalf of the residents of Atlanta and I wish her well moving forward in her career,” Reed said. “The Department of Watershed Management provides critical services to Atlanta residents and businesses, and I will ensure that it has effective leadership who will deliver operational excellence.”

Macrina was let go Friday because of a number of management missteps and questionable international travel, Channel 2 Action News reported.

Macrina came to the city from DeKalb County, where she was deputy director of the county watershed management.

She replaced Rob Hunter, who stepped down from the watershed department amid complaints from residents and businesses about billing and inaccurate readings, Channel 2 reported.
