You will get questions about what is your goal for these ponds, what kind of fish do you want, and such...I will let others tackle all that with you...and oh yeah...post some pics and that will help. What I will say is where I am in Kansas the drought still rages on. I (and others on this forum) have taken the opportunity to work on docks, piers and bridges...along with other things that can be done with low water. Decide where you want some of these if they do not exist already. Plan spots to hang out..beaches...firepits...campsites and the like. As for the fish...I would first be sure "all" the fish are dead. Seems like a pretty big body of water for that. If they ate all dead, then you need to try and figure if it is to shallow...or maybe to many fish (biomass) in there and the water quality deteriorated. Congrats on the new place and you have come to the right place for questions and info
