I thought I just add a late season note on water tank usage. The deer have been keeping my water tanks open enough for them to get a drink, even through lows of 0 to teen temps for several days in a row in two stretches. Ice was 4" thick in all of tanks except the hole they kept open. The pic numbers on these tanks has increase almost 2.5 to 1 compared from Sept to end of Nov vs Dec one till present. I've had every buck that has been on a camera other than my water tanks be photographed at my water tanks double digit times. In fact, there are several bucks that have only been photographed at the tanks. Every new buck that showed up after rifle season have been regulars at the tanks.
I removed ice and refilled the 5 tanks( each tank is 165 gallon) I have on Dec 6. We had some very cold temps prior to that and after. I had to refill the tanks based on cam pics over some of the tanks. On Dec 21 I refilled them. It took 440 gallons to refill them. I have no doubt that 50 gallons of the refill came from ice I removed but that still means they drank a lot of water in that 2 weeks time. The two newest bucks that showed up after the refill on Dec 6 have been every other day regulars at the tanks. I could have shot one of them at 50 yards with muzzle while I was in the stand. That buck is a typical 5x5 that would score in low 150's, the other new buck is a 6x5 that would push 160. Both on on the red light list and hope they'll be around next season. If it goes as it has in years past. They will be regulars next fall if they survive until then.
A great 6x5 (split g2, scores in low 170's) was shot Dec 4, 10 yards from one of my tanks. Water is in the top three of habitat manipulations that I've done to my properties to make them better deer hunting properties.
1. Getting to and from stand without deer sensing hunting pressure
2. Forest stand improvement
3. Water (there were/are two dirt dam ponds on mine but until I put tanks in, it really wasn't a factor. There are dams(from 10 yards to 25 yards away) on neighboring properties and a creek 400 yards north of my line.
4. Food plots
