Water Leak question...

On a 318 I finally tracked down my water leak. its coming from the water pump bolt that has exposure to the water jacket.
I tried tightening it, but if that does not work what have others done to avoid a leak?
The picture shows a Red circle on the bolt that is leaking. My Power Steering Bracket is partially blocking that nut.
Any suggestions will be appreciated. I'm getting ready for a long drive to get to the Frog Follies show in Evansville.
