# San Francisco king tides and high water in 1997

> In 1997, NOAA's San Francisco tide gauge recorded water high enough for FloodRoute's model to put at least one San Francisco road at risk on 11 days. The highest was 7.70 ft on Thursday, November 13, 1997, 1.01 ft above the tide tables, with 6 roads at risk, including Townsend Street, Mission Bay Drive and Channel Street.

**Estimates, not records of actual flooding.** Each day is NOAA's verified high water at the tide gauge, run through FloodRoute's flood model on today's roads and elevations, in dry weather. Drains, levees, tide gates, rain, road changes and elevation error all mean real conditions differed. Not for property, real-estate, insurance, lending, engineering or legal decisions.
