The old bridge just upstream from the Stevenot (49-bridge) has come up in conversation throughout the summer.  Many of us wonder when it will be visible from the highway and others have claimed to see it while driving past.

Last Friday we used Lowrance GPS and sonar to locate the old bridge.  While carefully watching the map and depth finder, heading toward the bridge we were in 136′ of water, the moment we crossed the bridge 108′ of water and then back to 136′ of water.

We made multiple passes with the exact same results, so we can confidently assume the top of the bridge is 108′ from showing.

The last time the bridge was exposed was from August of 1992 to January of 1993.  In that time the reservoir reached an all time low on October 1st, 1992 at 721.15′ in elevation. That is approximately 141′ in elevation lower than today.

Let’s all hope we don’t get to see the old bridge.
