Tried this once while in Oregon. Deer and elk loved it. Even a bear found it. However I went back for the season and someone decided they didn’t like that I had done this and destroyed my pretty elaborate set up. Beware most likely someone will find it and either sit it or like in my case destroy it to get the animals to come to where they are set up. Make sure and camouflage the crap out of your set up. Mine was not camouflaged enough. Pretty disappointed as it helped all the animals in the area I was hunting.
Not going great! I have not had a single visitor outside of rabbits since I set it up. I am honestly surprised.
Good news is I checked it last weekend on the 31st which would have been nearing 3 weeks since I set it up. with utilizing the enclosed barrel and small auto-float water bowl, The evaporation was next to nill. I could only add a half gallon of water to the barrel before it was topped off.
Even without activity, I left it up in case something finds it before my hunt starts on the 28th. I honestly think the last remaining "Known water" went dry in the area which prompted them to leave prior to finding mine. I had seen Antelope on every trip in there excluding the last trip.
I have not lost all hope on it working but I am not holding my breath. My only thought is I should have got it out sooner in the hopes they would find prior to leaving. I thought by putting out some shredded alfalfa that they would have picked that scent up and got them to the water.
