For the second time in less than 24 hours, families living along the Tittabawassee River and connected lakes in Midland County were ordered to leave home. The evacuations include the towns of Edenville, Sanford and parts of Midland, according to Selina Tisdale, spokeswoman for Midland County. Dow Michigan Operations is working with its tenants and Midland County officials and will continue to closely monitor the water levels on the Tittabawassee River, Schikorra said.
