Today’s Goal:To understand how water is absorbed into the ground.To be able to explain the difference between pervious and impervious surfaces.To learn about watersheds and storm-water runoff.

The rain’s ability to absorb into the ground depends on if the ground is pervious or impervious
In other words, . . . Can the rain get
through the surface or not?
When it Rains it Pours
If the ground is pervious, such as a grassy lawn, a forest, or a field, the rain can easily soak into the ground
When it Rains it Pours
If the ground is impervious, such as concrete driveways and sidewalks, asphalt roads and parking lots, and rooftops of houses, the rain cannot soak into the ground
When it Rains it Pours
When water soaks into the ground, the ground’s sand and soil act as a natural filter
When it Rains it Pours
When water runs over impervious surfaces, it picks up all kinds of pollution along the way
When it Rains it Pours
Everyone lives in a watershed
When it Rains it Pours
A watershed is the land where all of the water drains to a specific location
Mississippi
Cumberland
Big South Fork
Ohio
Bear Creek, Roaring Paunch Creek and Big Creek are
part of the Big South Fork Watershed....
Which is part of the Upper Cumberland
Watershed...
Which is part of the Ohio River Watershed....
Which is Part of the Mississippi River Watershed.
BIG SOUTH FORK TO THE MISSISSIPPI RIVER
When it Rains it Pours
41% of the United States eventually drains into the Mississippi Watershed which then empties into the Gulf of Mexico
That’s almost HALF of the entire United
States! Wow!

The key idea is that EVERY drop of rain flows somewhere
When it Rains it PoursKentucky is divided into 8 major watersheds.
When it Rains it Pours
Whether or not our watershed becomes polluted is largely up to US. . .
. . . because if it’s on the ground, it’s in your water
