Please Note:

In December 2023, the USGS relocated the gauge from the San Juan Hollister Road Bridge to a new location approximately 3 miles upstream at the Hospital Road Bridge. Flows above 1,000 cfs and stages above 13.0 feet are unreliable due to rating curve uncertainty. As the USGS continues to take additional measurements, the flow and stage estimates will become more reliable above these thresholds.

Plot Type:

Please Note:
1) Each individual timeseries plotted on the graphical river forecast can be toggled on and off by clicking the legend entry above. If the "Observed (Raw Data)" contains bad data and is toggled off, the plot will scale to the remaining timeseries.

2) At extremely low river flows, the "Observed (Raw Data)" may show readings below the lower end of the available rating table, while the "Observed (Simulated)" will only show values at the bottom of the rating table, creating a potential discrepancy between the two readings.
