This rating table shows the relationship between gauge height and river flow for the USGS gauge, id '11481000', located on the Mad River at Arcata, CA. Dreamflows generated the graph and table using USGS rating table data. NOTE: The rating table below was published Aug 28, 2020 and was valid only at that time.
