Here is some info generously contributed by member Capblack in an earlier Silverton Reservoir thread:
I saw some people asking for info on Silverton Res on here, and since I grew up less than a mile from there and spent my entire childhood fishing that res, except for when dad took me down the santiam, I thought I would put in my 2 cent worth.
First of all if your going to fish from a boat, try to get up the creek as far as possible, and bank fish, theres some very nice cutthroats in there. also the rock wall and anywhere towards the middle above the boat ramp is good. I saw the res when they let the water out for repairs, and the channel is from the inlet right down the oppisite bank above the bend. No more than 30 ft from the edge. Then when it comes around the bend, Its about middle of the res until it gets to the spillway.
If your bank fishing, anywhere to the left of the boat ramp as far as you can go is fine, and Ive seen people on the point doing pretty good when I was in a boat. a lot of people fish between the ramp and the spillway, but Ive never had much luck there, and its always crowded after they stock it. Its also very shallow towards the fence, you can wade across in the summer time.
As far as bait is concerned, stockers are all pretty generic, eggs, worms off the bottom if you blow them up to float, powert bait, spinners. If your going up stream for cutthroats, try spinners and drifting worms or eggs.
Hope this helps some of you, this is a very good place to take the kids, with them stocking it, and the restrooms and all. happy fishing, Brian
