Hey JTodd, Really glad you and family are OK. I agree with most posts and if you have the resources, like to control what species you have and what is or more importantly what is not eaten, other by humans, a redo would be in the works from my perspective.

It's hot and dry down there to mid summer most of the time. pump it down, rotenone the rest. Might even do a little dirt work too if a dozer and or backhoe are available. Might even be able to raise the Levee a bit more just for grins and deepen the pond a little unless you have packed clay bottom. Most of the land down there are not red clay like what we have in East TX, plus the water table is much closer to the surface down there for the most part.

Since the runoff from the river floods your pond it would be difficult to control massive river flood water and needs to be considered a part of what happens from time to time. Decades between events makes for a lot of good times in between, IMHO.

Good luck on whatever you do. Taking chances give chancy results, sometimes good. With known factors, chances are one gets known results, but as always on PB "It Depends"!

Life is more fun with a pole in your hand.
