Welcome to the forum PondsK8r. Glad you found us... The first pond you mention as being very shallow. Any idea of the maximum depth of this pond? Depth can be very important if you want game fish to survive the brutal winter months Michigan experiences. For most game fish, an absolute minimum depth would be 8 feet and that would probably be with aeration. Many of the pond owners on this forum have ponds in excess of 20 feet... If your pond doesn't have that depth, there are options for renovation if you goals are to grow game fish in it. Often times shallow ponds such as the ones your describing provide excellent habitat for wildlife though.
