I was watering some new trees that we have set out
this spring and I left it purposely so that the
water would create a pond above the burlap and
gently soak into the ground. I noticed after a few
waterings, as the new soil settled around the ball of the tree, that bubbles came up through
the small pool sometimes as the water soaked around the tree....These bubbles looked almost
identical to the ones that I have seen in my pond
and it made me compare the two situations. I know
the water was sinking around the trees and it
caused bubbles so I assumed that water seeping from the fish pond might cause bubbles as well...Just a thought. I don't have any muskrats but I do have some turtles.
