With floodwaters along the Mississippi River in the southern U.S reaching historic levels it’s time for Iowa to take a leadership role in helping prevent future flooding by investing in watershed improvement programs and conservation in Iowa.

Many people might not know what a watershed is. A watershed is basically a basin defined by highpoints and ridges that descend into lower elevations and stream valleys. A watershed carries water from the land after rain falls and snow melts. Drop by drop, water is channeled into soils, groundwaters, creeks, and streams, making its way to larger rivers and eventually the sea.

According to the EPA:

A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. John Wesley Powell, scientist geographer, put it best when he said that a watershed is:

“that area of land, a bounded hydrologic system, within which all living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community.”

Watersheds come in all shapes and sizes. They cross county, state, and national boundaries. In the continental US, there are 2,110 watersheds; including Hawaii Alaska, and Puerto Rico, there are 2,267 watersheds.

This is the connection between watershed and land management practices in Iowa and recent flooding on the Mississippi River. …more after the jump…
