It's leaking too much. But, don't panic yet. Watch it until summer, and see if the seepage slows. If not, consider taking corrective action this summer. Lots of suggestions, but as you progress through spring, watch the pond. I have a leaky pond, but the water is going around the dam, not through it. We tied it into two hills, and water pressure pushed water laterally, through the hills. We plan to use bentonite, after soils dry a bit. So, hang in there, study the dam more, then decide what to do.
