Iowa - Current Level to 300 feet
Being far enough away from the Atlantic Ocean, Iowa is much less susceptible to tidal surges or massive flooding. If there was a slow sea level rise that made its way up the Mississippi River, Iowa would start to be affected at about 480 feet of sea level rise (lowest point is where the Mississippi River meets the Des Moines River).
