As the Harris County Flood Control District collects and analyzes data, informational reports and graphics are made available to the public.
Estimated Maximum Inundation Exhibits
These inundation exhibits estimate ONLY where Harris County bayous and tributaries left their banks due to rainfall generated by Hurricane Harvey. The shaded areas do not show all flooding impacts throughout Harris County and do not necessarily indicate where structural flooding is or has occurred, since structure elevations and water levels vary widely throughout the inundated areas.
