Thanks for the quick response. Yes this pit is .52 miles (google earth) from the Rio-Grande River. Does that mean the water in my pond will be flowing and moving slowly through the sands? Is there a way to determine the flow rate? As far a flooding from the river is concerned. It is possible but not probable. There's a levy system between me and the river and the Rio-Grande is not so Grande anymore. As Far as stocking goes, very simple. Fl.LMB,CNBG, FHM, threadfin Shad. Maybe gizzard Shad in the future.
