In karst country, like right here in the Ozarks, the water on the surface and the water underground are the same water. đź’§

Across Northwest Arkansas and northeastern Oklahoma, rain that lands on a field can reach a cave spring in just a few hours, carrying whatever it picked up along the way. That is why what each of us does on land matters so much for clean water.

Through a partnership project with The Nature Conservancy in Arkansas and with funding from Arkansas Natural Resources Division, we are launching a new webpage to help local government and the public learn how karst works, why it matters for our region, and what you can do to help protect it:

We've reached the end of Stormwater Awareness Week—but protecting our water doesn't stop here!

Every day, small choices can make a BIG difference:

- Pick up litter
- Scoop the p**p
-Fix vehicle leaks
- Dispose of items properly
- Plant and protect vegetation
-Keep pollutants out of storm drains

You don't have to be a water scientist to protect water. You just have to care about where your water goes.

This Stormwater Awareness Week, let's make a commitment:

Be aware. Be responsible. Be part of the solution.

Happy Stormwater Awareness Week!

STORMWATER AWARENESS WEEK — DAY 5!

Did you know your yard can help manage stormwater?

Plants, trees, and healthy soil can slow down rainfall, help water soak into the ground, and reduce the amount of runoff flowing toward storm drains.

Want to make your yard more stormwater-friendly?

* Plant trees and native plants, they have longer roots!
* Keep healthy vegetation along drainage areas
*Use rain barrels to capture rainfall
*Add rain gardens or other areas where water can soak into the soil
*Leave grass clippings and leaves out of the street

And remember, don't mow all the way to the water's edge! A healthy vegetated buffer can help protect the stream bank, provide wildlife habitat, and filter pollutants before they reach the water.

Sometimes, letting nature do its thing is one of the best stormwater solutions!

STORMWATER AWARENESS WEEK — DAY 4!

ONLY CLEAN RAIN DOWN THE DRAIN!

Storm drains are designed to move rainwater—not trash, chemicals, paint, grass clippings, oil, chlorinated pool water, or other pollutants.

What goes into a storm drain empties into our local waterways.

So, before you pour, dump, sweep, or empty something into the street, ask yourself:

“Where will this go when it rains?”

If the answer is “the storm drain,” STOP! ✋

🌧️ Keep it clean.
đź’§ Keep it out of the drain.
🌎 Keep our waterways healthy.
