I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Samlesbury Bottoms Weir on the River Darwen, parking is minimal so you may have to park a fair bit away to get here.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 18/02/2024. It remains the responsibility of any pilot to check for any changes before flying at the same location.
