Explore the basin with our interactive maps!
Welcome to the Catawba Riverkeeper's new map to explore the Catawba-Wateree River basin!
This is a large basin -- 5,000 square miles with two million people. Each Monday for the next two months, we will be rolling out a map to help acquaint you with the basin. Where does your water come from? Where does it go? Where can I recreate? Who represents me in the legislature? These questions and more will be answered in our interactive map.
Explore the navigation to the top left to search for an address, change base maps, turn layers on/off, view the legend, filter (if available) or measure.
The layers have been compiled using publicly available data with tremendous refinement. Still, the data might not be perfectly polished. If you notice an error (or have a question), please contact email@example.com.
1/11/17: Who Represents Me? Updated House, Senate Districts
Legislatures in both North and South Carolina went back to work this week. With the election behind us, not only is it important to know who represents you and if that changed, but it is time to engage your elected officials. Get to know them, and make sure they know we need legislation protective of the water we all depend on and enjoy!
9/19/16: Thermoelectric Power Plants
Where does our power in the basin come from? A lot of people need a lot of electricity and a lot of water. And the generation of that electricity itself needs a lot of water.
9/12/16: Legislative Districts
9/5/16: Recreation Access: Launches, Gas, Restrooms, Marinas
8/29/16: National Pollutant Discharge Elimination System (NPDES) Permit Discharge Points
The Clean Water Act of 1972 created the NPDES permit program to regulate pollutant discharges and -- as they hoped to do by the mid 1980s and is in the name -- eliminate pollutant discharges. Basically, if you use water to handle waste, only return what you took out.
This week, we release a map of releases -- where pollution is permitted to be released into the Catawba River and other waterways in the basin. The basin currently has 272 active NPDES permitted discharges. Data for this map was filtered to not include inactive permits, though some displayed permits could have become inactive (a common trend as we had 550 active permits in the basin in 2007), and some new discharge points could have been added.
The data have been divided into two layers for two common types of NPDES permits:
Wastewater treatment plants (WWTPs)
- Treated sewage must conform to certain permit standards, but this effluent can still contain bacteria, nutrients and other problematic chemicals, including those not monitored in the permit (e.g., industrial chemicals, pharmaceuticals, etc).
- These are NPDES permits other than WWTPs and are often industry from chemical coating companies to paper mills to various other manufacturers that need to use and discharge water.
Also, layers from last week's release remain available. Click the layer button under the search bar to see a dropdown list of layers you can turn on and off.
8/22/16: Waterways, Basins and Public Water Supply Intakes

What's the name of that creek? Which sub-basin (creek watershed) am I in? Where is the precise location from which our water is withdrawn?
This first release includes the basic water features of our basin, including an outline of the overall Catawba-Wateree River basin! Exactly where does that line fall? Now you know! Within the basin are other layers. Click on the features for pop-up windows with information. You can always search for an address in the Search Bar and zoom out to see nearby features.
Perennial and Named Waterways
- This layer contains waterways from the National Hydrography Dataset (from USGS) that are classified as perennial (year-round, regular flow) or have a name. Must be zoomed in enough to see. Some segments might appear broken, which can happen because of farm ponds and re-routing (i.e., under a road).
- This is a subset of the Perennial and Named Waterways layer and will only display larger rivers and creeks. Only visible when zoomed out.
- The major, dammed-in-line lakes of the Catawba River with information on area.
- You know the overall Catawba-Wateree River basin now. What about the drainage areas for specific creeks? Basins are organized in Hydrologic Unit Codes (HUCs). The more numbers, the more detailed.
Public Water Supply Intakes
- These are the locations from which water is withdrawn for treatment and distribution in municipal water supply systems. Some municipalities sell water to other municipalities, and that information is included, too.
