I Would think Berttski has the right Idea. Dig some holes all around the pond close to the water, in the wet spots and also where the dirt is dry. That will give us more information to process.
The pond continuing to fill from ground water could, as Bill Cody says, cause some concern if and when the weather gets good and dry. That question will only be answered with some time maybe later this summer.
Let us know what you find out from the holes you dig.
