USGS gauges
70 U.S. Geological Survey stream gauges in and around Harris County, including the Brazos River at Richmond and Buffalo Bayou at Piney Point, with National Weather Service flood stages and record crests where published: all USGS gauges.
Why this site exists
Harris County publishes these gauges on an interactive map, which answers the question "what is the level right now" and then forgets. The county feed serves only each sensor's current value, so there is no public record of what a gauge read last Tuesday. This site records every reading as it is published and keeps it.
