I recommend Bent Rods Guide Service with Jordan Smith. I went on a sturgeon trip with him last March. He took use to a hole he knows and we caught about 50 sturgeon in about six hours. Only two where keepers, one that was a huge oversized brute that broke line before we could get him and the rest where undersized. All other boats around us only caught mabey three undersized fish per boat. His prices where good and he knew the river well. Here is his web site:
