When I troll for walleye stay in about 35-55 ft of water. I use a slow death, yellow smile with red and use a small sinker slide, 4oz sinker ball. I used 25lb braided and cheap 10 lb too attach the sinker ball. They way if you get hung up, you only loose your sinker.
I've been going out at Kellar marina
What part of lake Roosevelt do you go out at?
We got 3 walleye and 3 smallmouth bass. Only fished for 2 hrs, wind came up an got blown out. Still had a good time. Yes it is a beautiful lake!
Going this morning, gonna get a batch of walleye. 16 is the limit with no size restriction. Last week got 22 walleye and 6 smallmouth bass. Was a good day for 2 people. Like Mondays not many if any anglers out.
