Hi Cheri,
You're welcome.
Under the bridge is not a bad idea, as that creek water will be cooler. So, it's worth a try.
My buddies and I were there in a boat in June. The trout were everywhere...literally. We even found them next to the bank in only 4' of water. But, most were schooled up in a 30' deep pocket.
To find that pocket, walk out past the transportation site/lot. Go almost to the end of the point. Then, slip down to the creek side. Cast out to the east about 100 - 150 feet, and you should find that deep pocket. There should be some trout in there.
We did the best, by floating Power Eggs OFF the bottom, with the standard slip sinker set up. Casting from the bank, I'd use at least 1/2 ounce sinker so you can get out to the pocket.
Tight lines,
Jay
