My immediate inclination would be to investigate more closely the reason for their screaming---after all they may have been in distress from a source that was not easily apparent. They may have been sreaming for you to come and capture some large trout that were bothering them. If, after careful scrutiny, I was able to determine that they were screaming because I was there, I would leave quietly and courteously. I do not think you would be legally obligated to go away any more than you would if there were another fisherman there instead of three skinny dipping college girls.

Seems to me that part of the attraction of skinny-dipping is the element of excitement at the possibility of being discovered so, you may be the 'icing' on the cake, so to speak.

Thinking about legalities, if both parties are not prohibited from being at the location, then you have as much right to be there as they do.

Please turn your head so that it will not be evident that you are sneaking a peek.

I definitely stay and catch me the biggest fish.....
If they ask me to leave then I politely go quietly but I'm certainly going to stay..........

I don't know how long a gentleman would stay and observe, but I assure you that I would max out my gentlemanly time allowance.

You have no obligation to leave. It was their choice to be nude, not your problem. Maybe politely let them re-clothe. You might as well go, the fishing was probably ruined for the day.

You did not have to leave, but you did the right thing.

Never know what will happen when out on a fishing trip.

lucky you..i dont see how you would be in any toruble with the law ..you have the right to fish there

They were adults and so are you. But you did the right thing.

i dont know i dont think people go skinny dipping if they dont wanna be seen but i think u did the right thing
