There are 16 stream gauges along:

  • Crabtree Creek (Ebenezer Church Rd, HWY 70, Anderson Dr, Old Wake Forest Rd and US 1)
  • Walnut Creek (Buck Jones Rd, Lake Johnson, Trailwood Dr, S. Wilmington St, S. State St, Rose Ln and Sunnybrook Rd)  
  • Pigeon House Branch (Cameron Village and Fenton St)
  • Marsh Creek (Stony Brook Dr) 
  • Rocky Branch (Pullen Rd)

We use most of the gauges to track flooding. Others track wet weather conditions to see impacts to the sanitary sewer system.

Stream flow and rainfall tracking is in partnership with US Geological Survey (USGS).

​​​​​​As of January 2023, there are now rain gauges at all but two stream gauge locations (Capital Blvd and Anderson Dr), along with seven rain gauges at Raleigh Fire Stations.

Rain Gauges at Fire Stations

We installed new rain gauges at fire stations in Raleigh. We chose these locations because they provide 24/7 operations and are spread out across the city.

The rain gauges show how much rain has fallen in an area and feeds the data into Raleigh’s Flood Early Warning System to help adjust our Gauge Adjusted Radar Rainfall (GARR) amounts and predict potential flooding.


  • Easy access when repairing gauges.
  • Better predictions on flooding for first responders.
  • Efficient way to compare radar rainfall estimates with on-the-ground measurements.

Active Locations

  • Fire Station 5 on Oberlin Road
  • Fire Station 15 on Spring Forest Road
  • Fire Station 18 on Morgan’s Way
  • Fire Station 19 on Spring Forest Road
  • Fire Station 21 on Southall Road
  • Fire Station 23 on Pinecrest Road
  • Fire Station 26 on Barwell Road

During a Storm

Leading up to and during a storm we: 

  • Monitor rainfall and stream flow;
  • Identify flooding impacts; and,
  • Alert first responders early for road closures.

Stream gauges also help indicate whether or not a lake needs to be lowered before a storm to protect people and their properties.

Follow Water Levels

There are a few ways you can see the water and rainfall levels from the gauges:
