The two ponds would allow creating two diverse fisheries. For instance, want to catch some big catfish? pond 1. Large LMB and CNBG, fish pond 2.
A friend down in Dallas who has property about 80 miles East of Dallas has maybe 20 different ponds on his place, from 70 ac to >5 ac. The 35ac pond is managed for trophy LMB, and he loads it up with TSH. There also are BG, RES and Crappie in it as well, but the main focus is trophy LMB. His target is 12+# in 2 more years, and he's well on his way. Another pond (around 3 ac) has a good population of CC and CNBG, and just enough LMB to keep things in line.
