There are literally hundreds of wild pigs that come down out of the hills and root for food near the lake. I'm sure that they are decimating the hibernating Crawdad population. They also dig up acorns and everywhere there might be food they've dug holes 6" to a foot deep. I do a lot of fishing at night after work so, you can imagine how much fun I have avoiding their pitfalls without turning on my light and scaring every bass in the area.
Tight lines,
