An example is shown below over the Sacramento, California region. Recent rains<\/a> in California caused flooding in much of the state, including regions near the state’s capital, Sacramento, particularly along the Sacramento River. RealEarth provides a 14-day archive of the NOAA LEO\/GEO Flood Mapping Product (listed as River Flood: Joint ABI\/VIIRS), which is available on a daily basis. The product is an estimate of surface flooded water fractions, and can be obstructed by cloud cover as seen in the frame from 1-29-2023. While the area looks heavily flooded, it is important to note that many of these regions are actually agricultural rice farms<\/a> that intentionally flood surface areas.<\/p>\n\n\n\n

A flood gauge monitored by the USGS<\/a> shows a decline in water levels over the past week in Sutter County, CA, just north of Sacramento and along the Sacramento River.<\/p>\n\n\n
