How to read these numbers
Level is the water surface elevation the gauge reports, not a depth. Below bank is the distance from that level to the top of the channel at the gauge, using the top-of-bank figure Galveston County Drainage District 1 publishes with each reading. 7-day closest is the smallest that distance has been over the last week. History on this site starts October 21, 2026, so ranges and comparisons fill in over the coming weeks.
