The spillway, also called the salt water dam, sits high and dry on Thu Jul 26th during a dry spell in the San Bernard watershed. There is approx 12” of height between the waterline and the top of the dam and 6" of height on the other upstream side.
Compare the above photo to this one shot on April 10, 2017. 2017 was a big year for water over the dam!
The Phillips 66 spillway is located on the San Bernard River approx two miles upstream from Hwy 35 and Hanson Riverside County Park west of West Columbia. The spillway contains the fresh water flowing downstream and stops the upstream flow of salt water. The San Bernard is the source of water for the Phillips 66 Old Ocean refinery.
