14.7' -
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' -
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' -
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.
