Reading a creek using tried and true techniques really serves only to provide you with pre qualified places to start test panning.
Test panning is really the only sure fire way to know whether you are onto a pay streak or not. (if dredging then dredging test holes, but you still have to pan the cons)
Different creeks in different parts of the country require different strategies.......
For instance, on small creeks in glacial gold territory looking for recent "flood gold" I've found that by first locating the path of the black sand and then test panning toward the middle of the creek side of the black sand streak provides the best results. Other creeks and types of gold sought after require different strategies so you just have to get your feet wet and "go for the gold"
There is no substitute for hands on experience and gold is where you find it, and sometimes it's found where you would not think it's supposed to be.
But for the most part it's right where it should be, that is unless someone beat you to it.
