I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
As you enter Salters Lode from Wisbech, on the right is a small bridge that crosses Well Creek river. Cross the river and there is room to park. There are 2 small rivers with sluice gates that are interesting but there are power lines here. Instead if you follow the concrete road for about 100 yards there is an embankment where you can take of and land. Here you can get some great shots of Denver Sluice and the River Great Ouse
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 12/12/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
