Salt Creek Watershed Project

Waverly High School Salt Creek Watershed Study


The city of Lincoln lies in a roughly elliptical dish, carved from the once rolling landscape by Salt Creek and its smaller tributaries which merge.

The origin of these salt marshes lies under the region's mantle of fine loess soil and along the network of streams which have carved through it.

The main source of the saline waters lies deeper, in ancient shales laid down in Cretaceous times.

Cretaceous times are also known as the Age of Reptiles.

This occurred some 70-160 million years ago, when much of central North America was covered by a vast inland sea.
