Stream Sensors, Rain Gauges, and Weather Stations 

Starting in 2021, Cary began installing stream sensors and rain gauges within its waterways. The sensors provide real-time stream elevation data while the rain gauges record rainfall accumulation and intensity.

This data is used to develop and calibrate basin models to assist with stormwater planning and floodplain improvements as well as to send alerts. These IoT technology and data analysis projects are part of the Smart and Connected Cities Program that supports data-driven solutions intended to enhance the quality of life in Cary.

In 2024, weather stations were installed at most Cary Fire Stations. They include additional typical weather data.

Visit our interactive stormwater dashboard for maps and real-time data from stream sensors and rain gauges. Cary is in the process of adding the weather stations to the dashboard. You can also view, download, or even subscribe to historical information using our stormwater dataset in Cary's Open Data Portal. 

The NC Department of Public Safety also hosts a website that shows stream data for all of North Carolina; users can sign up for alerts when streams reach flood stage.
