During periods of low water, I've been able to find water by simply walking down the drainage from a primary watering source until you find water. While I've never stayed at Mollies or Russle, I've have been at Brich Spring (Site #113) when the piped water source was bone dry. I simply walked down the drainage for less than 100 yards and found plenty of water still flowing. However, for these kinds of seeps, it really helpful silt prefilter (I use the SweetWater filter with the
Silt Stopper prefilter).
