Description: Dams are being represented as point features. A spatial representation of dams found along the hydrography network that generally serves the primary purpose of retaining water. The feature locations were derived from sub-meter GPS collected since the year 2000 and conversion efforts from paper and digital construction plans. Key attributes include AssetOwner, AssetMaintainer. Note: Null Field values mean the Data is not Available or Not Researched. NextDownID fields that equal -1 mean there is no feature downstream.
Description: Watershed is a spatial representation of watersheds in Oakland County. Though the watersheds extend beyond the county boundary, they are clipped to the follow the boundary. This polygon feature class was created by using DEMs. Different cell sizes were used for different watersheds.
