Phase 2 floods (shown as purple on map) inundate a wider area and may cause significant damage. The large phase 2 flood depicted on this map is approximately what occurred in December 1975 which was estimated to be a 10-year event (a flood that would have a 10% chance of occurring on any given year)

Gauge heigths (measured in feet) indicate level at which the flood phase begins at the gauge location. Flood severity may significantly increase as the flood moves from the upstream to the downstream locations.

Phase 3 floods (shown as orange on map) can cause catastrophic damage in the valley. The very large phase 3 flood depicted on this map is the FEMA mapped 100-year flood. This flood would have approximately a 1% chance of occurring on any given year. If such a flood were to occur, many hundreds of homes would be flooded, thousands of people may have to be evacuated, and numerous public facilities and businesses would be inundated. In some neighborhoods flood waters would be deep and currents swift. Many roads would become impassable and extremely dangerous to use. The 1990 & 1995 floods were smaller phase3 floods. As a result portions of the phase 3 areas were flooded in 1990 and 1995. Caution: Under extreme conditions a flood greater than the 100-year flood can occur.

Phase 1 floods (shown as green on map) inundate low areas near the Skagit River, may cover a few small sections of roads, and occur every few years on the average. These floods generally do not cause significant damage in the Skagit River Valley. A large phase 1 flood occurred in December 1989. W
