Trinity - At Douglas City

This rating table shows the relationship between gauge height and river flow for the CDEC gauge, id 'DGC', located at Douglas City, 0.8 miles below Hwy-299 bridge, CA.  Dreamflows generated the graph and table using CDEC rating table data.  NOTE: The rating table below was published Feb 21, 2026 and was valid only at that time.  The relationship between gauge height and river flow may change over time and therefore the older the rating table, the less reliable it is likely to be.  The graph shows the range of data of primary interest to boaters, while the numerical listing gives the full range of available data.
