Eagle Creek Reservoir: Solution to an Environmental Problem (GM-09)
In the spring of 1958 a destructive flood swept through the normally placid Eagle Creek valley in northwestern Marion County. Levees were constructed as a quick solution, but doubt about their ability to control flooding and the need for another source of water for Indianapolis led to the construction of a flood-control reservoir by the U.S. Corps of Engineers.

Construction was made possible partly by glacial till along Eagle Creek valley. Had the underlying sediments consisted of sand and gravel or other porous materials, impounding so much water would have presented difficult engineering problems. A thorough understanding of the subsurface geology was essential.
