This lake was recognized to be Fleets Dam in Barnsley. Thank you all so much for the help!

The second photo kind of looks similar to Horbury Lagoon, but I could not find any pegs there, so I'm not sure...

Hello, I wanted to locate where those two pictures were taken. These were taken four years ago by a friend with whom I have lost contact since, possibly somewhere in Northern England. Judging by the plaque with a number, I assume it is likely a fishery, which is why I am posting this here. Sadly I don't really have any more information, other than it seems to attract swans. Any help would be appreciated.
