It’s Tuesday Trivia time, brought to you by the Upper Guadalupe River Authority: Protecting our Guadalupe River through education, monitoring, and planning.

Read on for tips to answering this week's trivia question:

Have you ever sat along the bank of the Guadalupe River and wondered, “How much water is flowing by right now?”  That amount is called the streamflow and there is no need to wonder how much is flowing by because we can measure it!  Streamflow is the volume of water moving past a certain point and it is often measured as cubic feet per second or cfs.  A cubic foot is about the size of a basketball, so if the Guadalupe River in Kerrville is flowing at a rate of 100 cubic feet per second, envision 100 basketballs moving past each second.

 Streamflow is always changing, from day to day and even minute to minute, but by using technology, we can accurately measure those changes overtime.  The US Geological Survey operates thousands of continuous streamflow gaging stations across the country.  USGS has six streamflow gaging stations in Kerr County supported through funding partnerships with UGRA and the City of Kerrville.  It is important to have reliable streamflow data to track changes overtime and especially during floods.  The USGS streamflow data is available online and updated at least once an hour.    

A key component to understanding your flood risk is being aware of rainfall upstream of you.  A watershed is the area of land that drains to a common creek or river.  When it rains anywhere within the watershed boundary, water flows into the river and creeks and begins moving downstream.  Therefore, flooding can occur in areas where it did not rain or long after the rain has stopped. 

Accurate and up to date streamflow data, rainfall reports, soil moisture levels, and weather forecasts are different types of information used by emergency managers to make flood predictions and issue flood warnings.
