How to read these numbers

Level is the water surface elevation above mean sea level, not a depth, so it is only comparable between readings at the same gauge. Below bank is the distance between that elevation and the top of the channel at that crossing, using the reference Harris County publishes with each reading. Closest in 7 days is the smallest that distance has been, from hourly averages over the last week. Each gauge page has the full history.
