i looked at the photo posted on your thread,.. i am no expert, but last week i did help stock on a stream which did had a high bridge,, i had waders so i volunterred to wade out,.... the trout were lowewred in a bucket by rope, the guy told me,........ just don't let the bucket go in the water, so i grabbed the bucket when it was lowered and i let the fish go easily,.. i was not aware, some one just emptied a bucket from the side of a high bridge,..
