In the lower C below I-5 any kind of anchor will do for springers, I anchor my 16 foot smokercraft with 45 lbs of chain like I do in any river. It's only in that oversize sturgeon water upriver that you need the fancy anchor system. For springers you never need to fish in over 20 feet of water and you avoid the fast stuff, as the fish travel along the shoreline and avoid the fast stuff themselves. So no sweat, whatever sled anchor you have will do fine.
