A few species can live in lakes. They are found across the U. Mussels live on the stream bottom, often completely burying themselves in the substrate photo leaving only their siphons exposed. They are hard to see because they blend in with the bottom and because any exposed part of the shell grows algae. Both dams were installed to serve as hydroelectric plants.
Dams disrupt the normal flows of rivers. Water becomes impounded upstream of the dams, creating artificial lakes. Norway Dam located at the outlet of Lake Shafer. Lake Shafer hosts the popular amusement park, Indiana Beach. Lake Freeman is decorated with many private homes and is popular for seasonal recreation, such as boating and fishing.
Many local businesses depend on recreational activities in the lakes. Sometimes we encounter challenges and conflicts while conserving endangered animals such as mussels.
Changing weather conditions often cause fluctuations in the flow of the Tippecanoe River. In times of drought or abundant rainfall, water levels will vary, with impacts to river users and residents of lakeside communities. To ensure the survival of endangered and threatened mussels in the Tippecanoe River, the U. Fish and Service has provided guidance to NIPSCO to avoid take of federally listed species by maintaining natural run-of-the-river minimum flows downstream of Oakdale Dam and eliminating large fluctuations in those flows during times when mussels are most vulnerable.
