I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission obtained.
This is clearly signposted as a private fishing lake with no public access.
I parked in the area indicated and spoke to one of the fishers. When I explained I just wanted to take some aerial photographs but was concerned about disturbing the other fishers he just said, "Send it up, mate! Send it up!"
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 05/09/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
