This water level monitor is located in Clear Lake Park near the northside of NASA Rd. 1. The page displays the current water level. Look at the table on the lower left of the page. It shows readings in the past 24 hours with the times read and the levels.

From my observations, the water level is too low for launching a boat when it shows 0.5 ft or lower. Large boats may have trouble launching when it is be ow 0.55 feet. Unfortunately, the station seems to report to the internet less frequently when the level is low, but that too may provide guidance as to what the level is: ii no readings are shown, it is probably because the level is very low.
