A County Drain may be an open ditch, stream or underground pipe, retention pond or swale that conveys storm water. These drains become designated as County Drains through a process where a local city, village or township petitions the Water Resources Commissioner to establish a County Drain. In some cases, property owners may also file petitions to establish Drains under the County's jurisdiction based upon the  Drain Code of 1956, Act 40. This Drain Code established by the State of Michigan is the guideline followed by the Water Resources Commissioner in the operations and classification of drain systems in Oakland County.

Not all drains are County Drains.
There are other drains in Oakland County, including roadside ditches, pipes and culverts under roads that drain state highways and county roads. These are maintained by the Oakland County Road Commission and/or local public works departments. Some local municipalities (cities, villages and townships of Oakland County) maintain and operate their own storm, water and sewer lines, and have public works departments that handle requests and information about those services.

In addition, drain systems that are not County drains and are not along roads may also be the property owners' responsibility.
