Mill Creek Hundred in Newark in New Castle County, Delaware — The American Northeast (Mid-Atlantic)
White Clay Creek
A nationally recognized waterway.
Only a select group of rivers in the United States, less than ½ of 1 percent, are designated into the National Wild & Scenic Rivers system. The White Clay Creek is one of them.
White Clay Creek watershed achieved this federal recognition in 2000 because of its outstanding natural, historic and cultural features. The "heart" of this unique bi-state watershed is nearby White Clay Creek State Park and to the north, White Clay Creek Preserve in Pennsylvania, providing important recreational opportunities and scenic beauty in an increasingly urban area. The White Clay Creek and the water in its aquifers are a source of drinking water for thousands of people.
A Partnership: Wild & Scenic River Needs You!
The federal designation helps to preserve watershed features that maintain water quality, natural resources and overall quality of life. The federal government does not own or manage lands within the White Clay watershed, but instead works with local partners to protect the streams.
Your help is needed to reverse the effects of decades of agriculture and development that have negatively impacted White Clay Creek. Excess fertilizer, animal waste, leaking septic systems, soil erosion, and hard surfaces such as roads and parking lots have degraded water quality and stream habitat. More than 2/3 of White Clay stream miles are now listed as impaired or polluted.

10 simple things
To prevent stormwater pollution:
1. Keep litter off the streets so it doesnt wash into storm drains and then into local creeks.
2. Dispose of hazardous household wastes and prescription drugs at designated collection sites.
3. Only apply fertilizers and pesticides sparingly and responsibly.
4. Install a rain barrel or rain garden to capture and soak in stormwater.
5. Scoop the poop, then trash it. Pet waste carries with it bacteria that is harmful to human health.
6. Plant more trees along the creek instead of mowing up to the banks.
7. Create wildlife habitat by planting a low maintenance landscape using native plants.
8. Wash your vehicle at a car wash or on the grass.
9. Service your vehicle regularly to prevent oils and other fluids from leaking into storm drains.
10. Only drain pool water that has been tested as chlorine free over grass. Untested watershould never be drained over grass or pumped to storm drains.
Remember: Keep as much water as possible off paved surfaces. Keep the water that does run off, as clean as possible.
