Just finished reading "Perfect Pond" and "Just Add Water." Any thoughts on my South Louisiana pond renovation plan (see attachments) from a vegetation and habitat standpoint? Should I designate a 4-5ft sand-gravel shelf for BG spawning somewhere? Should I consider expanding one of the shallow (1ft) shelves for attracting waterfowl?
The existing pond is the red dashed outline and is about 0.9acre. The current redesign is about 0.5acre though I'd like to increase that if I can find someone to take some dirt and reduce my cost. The main reason I want to increase it is to increase my average and maximum depth (limited currently by narrow width) and to give more acre feet of water for fishing, paddling, and swimming!
Don't worry about attracting waterfowl. Where you are, that's likely anyway. I'd make a spawning bed/shelf adjacent to your fire pit area. That's a great place to sight fish when sunfish are nesting. Make it about the size of a pickup truck, about three feet deep.
Lots of other suggestions in the two books you read.
Teach a man to grow fish... He can teach to catch fish...
It's 0.9 acre now, per the faint dashed line you can see inside of the property line and outside of the blue pond redesign (the redesign is smaller, 0.5 acre or so). Not sure where you see a flooded house. Sorry if the image isn't clear, I had to resize the attachment for it to fit and it's not as clear as the 2x3ft printed layout I have at home.
