This may be a goofy idea, but has anyone ever walked along the bed of the Arkansas River during low water flows, downstream of south Tulsa say in the Bixby or Broken Arrow areas? I was thinking of spots where I could let my dogs run loose and go swimming without bothering anyone, while I walk along the sand bars behind them. I know shifting sand can be a danger, but has anyone ever done this, and if so, where did you gain access to the river?
