Most nights, not long after dark, my ponds have a mist on the surface. Cool water, warm nights or vice versa.
The green light on my rifle won't penetrate it, and my eyes sure won't.
I have some 330s, and a couple of foot traps, but my dogs make a circuit run all around the pond edges sniffing out what may have been down there the night before and they go swimming a couple times a day, even in January.
This is why I want to use snares, tho I have no real experience with them.
Dunno what these beaver are up to this time around. No lodge building, not plugging up drains either like last year. Seem to be content just to eat the lily pad rhizomes off the bottom of the ponds, but I know that 'good' behavior isn't going to last.
