my dad just purchased a 250ac lake in south dakota. we would like to stalk it with perch and walleye. is there any info out there or does anyone have any suggestions. similar lakes in the area have good populations of perch and walleye. do we need pike too? would bg hinder perch growth. lake is 12-14' deep with shallow bays. crystal clear water. cormorants in the area. we have fished it with no success. underwater camera shows it has carp present otherwise little is known about current fish population. thanks for any suggestions.
