The TRCA's flood monitoring gauge network spans the GTA, continually monitoring in-stream water levels at TRCA dams and river stations. Real time stream flow, water level, and precipitation information is available. While designed as a portal for Flood Duty Officers, limited access to the website and data is available to the general public. For more information visit the TRCA's Main website at
