As further proof I have uploaded a picture of a dead one, it as you can see, it could not manage to get into the water, it had started to camouflage itself but expired due to lack of shallow water.

I await proof from yourself to at least give substance to your hypothesis.

Case proved I think.

Your case is flawed Dave your pictures only show river dwelling trolleys which are a different beast than the ones we are currently studying. I refer you to post 55 and the attached photos clearly showing at least four trolleys in what judging from the water mark on the wash wall is at least three to four feet of water , i also can vouch personally for the depth of that particular pond of water it is hall street pound and lock which at its deepest is about five to six feet deep, you will also notice that there is a picture of the trolleys close cousin the pram which is also pictured in the deepest part of the pound. Case proved i think you will find my good man.
