Mi. American - Above Tunnel Chute

This rating table shows the relationship between gauge height and river flow for CDEC gauge id OXB, located on the Middle Fork American River (on river right, about 1.5 mile below Ralston Dam), CA. Dreamflows generated the graph and table using CDEC supplied rating table data. NOTE: The rating table below was published Oct 27, 2009 and was valid only at that time. The relationship between gauge height and river flow may change over time and therefore the older the data, 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.
