I am just hoping the new pond fared better. I am pretty confident that the LMB, RES, BG, and CC in the old pond has some survivors of each species. I am more worried about the large YP we had stocked in the new pond last fall. My hope is that with little plant material in the new pond, the O2 stayed high enough to bring them through. I am planning aeration for the old pond, but he new one is too far from electric. My hold up on aeration in the old pond is digging the trench from the barn to the pond.
