[1] In the 1936 centennial history of Liberty Township, the nineteenth century Salt Creek watershed is described: "As the years passed the land has been drained by various ditch projects and the forests have bowed before the axes of the pioneers and their descendants.

Such maps published as late as 1876 show a great expanse of water in the northwest, spreading over acres of land which are now the fertile fields of August Hockelberg, Daly Brothers and Julius Turk.

[3] The Salt Creek watershed covers 19% of Porter County and 49,573 acres (20,061 ha), including the communities of Valparaiso, South Haven, Portage and Burns Harbor, Indiana.

Many rare species in the Salt Creek watershed are found in Samuelson Fen and related habitats at Imagination Glen Park in Portage.

Although they are no longer on the Indiana list of endangered species, both the American badger (Taxidea taxus) and bobcat (Lynx rufus) have been found within the Salt Creek watershed in recent years.

[5] Beaver create wetlands which remove sediment and pathogens and increase trout and salmon abundance as their ponds make ideal fish-rearing habitat.

[6] Contrary to popular myth, most beaver dams do not pose barriers to trout and salmon migration, although they may be restricted seasonally during periods of low stream flows.
