Puppy in training

I have a 4 month old silver lab that I’m training for a gun dog. She’s doing great in the yard retrieving bumpers but I need a pond and somewhere I can shoot blank rounds.. I am currently in a neighborhood and don’t even like to blow my whistle due to disturbing the neighbors.
I am in the Birmingham area near leeds to be exact. Anyone have any suggestions on where I could go? I really don’t want to travel to far as I would like to do this on occasion throughout the week.
Thanks in advance

If you got 4x4, I know where some old coal ponds are not far from you

take him to bps and train him in the little ponds there.lol
