Anchor scope... Drift sock... Thoughts on this situation

Kinda curious what type of scope you guys like to see when you're anchoring you yak in the river. My Willamette sturgeon hole is basically a giant eddie (a 100+ft deep Eddie) and there really isn't a whole lot of water flow, especially during an incoming tide. Even on an outgoing tide, it's not uncommon to see the surface water flowing upstream!

With the way the water flows, I'm having a tough time anchoring securely. I suppose this would be a good place to add a drift sock, but i'd have to get it down a bit to find water flowing the right direction...

I would normally let the current help set the anchor and use the drift till I felt the scope was, say, 2-3x (low because of low flow) but with lack of movement, I'm having a tough time... Last week I didn't even drift a foot as I let 115' of line down to the bottom. But after a family out wakeboarding passed a few times, I actually ended up losing my hold and dragging anchor (well, not dragging since I was in slightly shallower water then I ended up in)...

generally speaking if there is not enough current to straighten out your boat there won't be enough current for your drift sock to do much good either, it may help a little but most times it just sinks and swirls around with you. The same currents acting on you are acting on the sock. If you are in a back eddie and getting pushed upstream etc. the best bet is to try to find the current seam and re-anchor. The deep holes in that part of the river are full of eddies and boils and are hard to anchor straight in no matter the craft.  This time of year I would fish current with a drop off (eg, 25 to 60) before I fished deep water with no current.  Or just time your fishing when the tide is pulling, it can make a huge difference.
