It's about 2 acres. It has a manmade dam on the south and spillway, probably no more than 6' in the center, with a feeder creek on the north. Trees all along the west side, mostly bare on the east but lots of moss cover.
I haven't seen carp in it. I know there is bream, crappie I think, and cats I think. And of course Largemouth.
I've not heard a beaver slap in the wild. I watched youtube video of it, and the sound is different I think.
This was more of kerplump sound and not a slap. It was not on the tree side, but the moss side.
I haven't fished the pond in a month and I suppose a beaver could have moved in. I'll have to check for sign next time I'm there in the daylight.
There is old sign, from I'd say 2-3 years ago when I fished it in the spring.
