The following river flow graphics are produced by the National Weather Service's "Advanced Hydrologic Prediction Services (AHPS)". If flooding is expected, the graphics will show forecasts of expected river flow and stage. If no flooding is expected, the graphics will show observed flows and stages for the past few days. The graphics are updated at least once each day, and may be updated more frequently during flood periods.
