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.

Flood Impacts
114.0 Feet	Designated flood stage left bank.
113.8 Feet	Design overflow level for M&T, 3Bs and Goose Lake flood control facilities to divert flood flows into Butte Basin. M&T overflows close River Road from Ord Ferry Road to Chico Road. Ord Ferry Road is already closed.
110.3 Feet	Head cuts in 3Bs silt weir start overflow into Butte Basin, flooding dips on Ord Ferry Road west of River Road. Persistent flows at or above this level increase flooding in Butte Basin. Ord Ferry Road and additional roads in Glenn and Colusa counties are closed due to flooding.
