Description:

Freshwater estuaries are a unique ecosystem. They form as a freshwater river or creek empties into a large lake. The different chemicals and temperatures of the river and lake waters create the estuary. Old Woman Creek National Estuarine Research Reserve, near Huron, Ohio, is the only reserve that monitors a freshwater estuary: where Old Woman Creek empties into Lake Erie.
