So I am hunting a pretty low deserty area around 6500ft and we think we know a water source a particular group of bucks are using. Sitting the water is not an option (watering in the dark) but we think we have there travel route figured out and they don't make it to cover before it gets light. We want to try setting up along this travel route but I'm curious do these deer need to water every day? It gets to be 90-95 degrees in this area. Assuming there hasn't been rainfall in quite some time how often will a deer come to water?
