Records from the City of Ann Arbor.

Residents downstream of the Barton and Argo Dams were sent a mailing with evacuation routes and other emergency plans should there be a failure of these dams. They anticipate several bridges over the Huron River to be unsuitable for travel, and call for shelters at Huron and Community high schools.

Additional records requested related to dam safety were denied by exemption in MCL 15.253(1)(y)
