What Floods at Each Level
14.7 ft
At 14.7 ft, developments on the lower Santa Clara River near St. George and the St. George golf course will be threatened. Due to a large engineering effort, the Santa Clara River cannot change its course through St. George. As a result, flood damage is now limited to adjacent roads, bridges, and the St. George golf course.
14.3 ft
At 14.3 ft, the Santa Clara River as it flows through St. George will experience damage to adjacent roads and bridges. Due to a major engineering effort, the Santa Clara River cannot change its course, and damage has been reduced from prior years.
13.9 ft
At 13.9 ft, the Santa Clara River will damage adjacent roads and bridges. Post-2005 engineering work done on the channel now restricts the channel morphology of the river, and as a result, the flood damage experienced during 2005 is no more.
