10-Day River Level Probabilities

Instead of a single forecast line, this chart shows a range of possible river levels over the next 10 days. The shaded bands represent different likelihoods — darker shading means more likely outcomes, lighter shading means less likely but still possible. Colored horizontal lines mark flood thresholds. This helps you see not just what's expected, but how confident the forecast is.

Short-range probability chart

Weekly Chance of Exceeding Levels

Each colored bar represents one week over a 90-day period. The colors show the probability that the river's peak level will exceed a given height during that week — warmer colors mean a higher chance. Read up the vertical axis to find a water level you care about, then check the bar color to see how likely the river is to reach it. This is useful for spotting which weeks carry the most flood risk.

90-Day Chance of Exceeding Levels

These charts compare the current flood outlook to historical averages over the next 90 days. Two lines are shown: a current forecast line and a historical average line. When the current forecast line is above the historical line, the river is more likely than normal to reach higher levels. When it's below, conditions are expected to be calmer than usual. The horizontal axis shows water levels, and the vertical axis shows the percent chance of exceeding them.
