This image from CORA captures historical maximum water levels for the entire South Carolina coastline. Water-level observations were previously only available from one location, a tide gauge represented by the blue star in the image. The CORA dataset fills gaps in water level observations between tide stations providing historical water levels at each of the red, orange, and yellow dots, spaced every 500 meters along the coast.
