Indiana Dunes LakeshoreMost people probably don't think of Indiana as a major beach destination. However, Lake Michigan forms miles of lakeshore along northern Indiana where time and nature have created beautiful sand dunes. Save the Dunes is a leader in the community to protect the Lake Michigan basin and conserve Indiana's lakeshore. Research conducted by Save the Dunes Conservation Fund, during the development of the Dunes Creek Watershed Management Plan, found that leaking wastewater from aging and failing septic systems is a major source of E. coli and poses a serious threat to water quality in Dunes Creek in northwestern Indiana's Lake Michigan basin.
