The Vermilion River is a 269 square mile watershed that runs through parts of five counties (Richland, Ashland, Lorain, Huron, and Erie) before it empties into Lake Erie’s Central Basin in the City of Vermilion. The predominant land use within the Vermilion River basin is agriculture, at 73%, followed by wooded lots at 25%. The remaining 2% of the land is occupied by wetlands, open water and urban areas.
The upper portion of Vermilion River and its tributaries originate in the Erie/Ontario Drift and Lake Plain (EOLP) ecoregion consisting of low rolling hills and end moraines blanketed with low line drift and lacustrine deposits. Soils are less fertile than other ecoregions in Ohio, but support farming activities such as raising livestock, corn and soybeans. The mid-section of the watershed in Erie, Huron and Lorain counties flows through the Eastern Corn Belt Plains (ECPB) ecoregion which is characterized by rolling till plains and end moraines. Rich and well drained glacier deposits of the Wisconsinan age support extensive production of livestock, corn and soybeans. The lower portion of the watershed is located in the EOLP ecoregion. In contrast to the upper watershed, this portion of the ecoregion is characterized
by nearly level coastal lacustrine land with beach ridges and swales. The lacustrine deposits and lake effected climate support the production of fruit/vegetables and nursery crops.
