Fished below John Day Dam for shad and sturgeon and was able to have the best day oversized sturgeon fishing trip I have had yet. There was no shortage of bait to be caught either, which is always nice. We went 6-9 on the sturgeon all from 7' to 8.5' so we got our work out in this day. We were using whole shad with 10oz cannon ball and 12/0 hook. Couldn't ask for a better day until the wind came up. That comes with the territory down there though.
Remember if you do fish below John Day there is a 2.4 mile deadline you have to be below to fish for sturgeon. The marker is the grain elevator on the Oregon side. If you are below that you are good.
