I tried creek walking direcly adjacent to a spot I've found thousands of artifacts in.
Did not find even so much as a chip or flake. Other people I have met have had some luck. Waste of time for my areas. Too much competing media in the creeks here.
Now if you have a muddy bottom branch with no gravels, might be way different.
I've found some pretty decent stuff where washes and erosion went through a camp, or the banks changed a bit. Mostly the good camps I've found are above all that. FEMA should use the camps as a basis for 500 year floodplanes.
