What happened at the pond?

[Scott the fishman]

Okay so i woke up early today and rode my bike to my local pond. Small lake only a hand full of people fish the lake. All my fishing buddies where still asleep so i was by myself. I went to this small point my cousin showed me he said a 3 lber is usually there. I cast how nothing and was fishing there for like 20 mins. I here a bass jump and see the splash. So i go and look to see if i can cast there. I then see some mud kicked up and thought it was the carp in the lake (carp, koi, and two snapping turtles) then i see some more mud kicked up like 30 feet away they charge at each other and create this huge wake both of them and splash. i didnt see any outlines of fish or turtles i was kinda freaked out because i go this lake everyday i see the turtle often and sometimes the koi but i have no idea what this. then i go to the other side and fish this one sunken tree and this GIANT splash and when i say big the ripples went across the pond (the pond is about 2 acres) i didnt see any trees the fallen in the big splash was like 40 feet from the first splash thing. I have no idea at all what it is. There are no pike pickerel musky walleye none of those fish in the lake. only large mouth bass blue gill and some small cats. my only guess would be the two snapping turtles. does anyone have any other ideas or similar stories?
