What features are included in the Hydrology dataset?
Lakes, rivers, & open drains are included in the dataset. These features were digitized from the orthophotography. The Lakes file includes all open water sources. The Rivers file includes all rivers, streams, creeks, & open drains. Names of the County Drains were obtained from maps provided by the Drain Commissioners Office; no tile drains have been included in the hydrology dataset. Private drains have a unique naming scheme composed of the township and section where the drains are located.
