Your alternative theory is more complicated than your first one; your first one was also similar to the one I proposed on the previous page.
With respect to the zombies finding the reservoir camp, the humans generated noise, and there was traffic in and out of the place, some of it noisy too. At the time, I thought they were generating enough stimulus to attract zombies.
