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
35.0 Feet	People in Orick should evacuate oustide of the Orick Valley immeidately. The river is at the top of the levee (or overtopping) near the Shoreline Fuel Mart on the left/south bank & Hufford Road on the right/north bank. The levee protecting Orick is at imminent risk for failure. Levee failure will cause catastrophic flooding outside the levees, creating major safety hazards and inundating homes & businesses across Orick. Floodwaters will make portions of Highway 101 and other local roads impassable.
33.0 Feet	People in Orick should be ready to evacuate outside the Orick valley. Time for a safe evacuation becomes critically short, especially for people who need more time or have limited mobility. Follow direction of public safety and emergency response officials. The river is within 2 feet from the top of levee near the Shoreline Fuel Mart on the left/south bank & Hufford Raod on the right/north bank. The levee protecting the town of Orick has an elevated risk of failure.
32.0 Feet	People in areas protected by the levee within Orick should closely monitor river forecasts & be prepared to evacuate outside the Orick valley if water levels are predicted to continue to rising. People who need more time to evacuate, especially those with limited mobility, should consider taking early action. The river is within 3 feet from the top of the levee near the Shoreline Fuel Mart on the left/south bank & Hufford Road on the right/north bank. The levee protecting Orick is at risk for failure.
26.0 Feet	Officials responsible for the levees & emergency response begin patrolling to look for problem areas that can threaten the integrity of the levee such as seepage, boils, erosion, debris jams, cracks, or sloughing. Closely monitor precipitation forecasts & river forecasts (stage & flow) & be area of the potential for rising water levels.
