Jayman,
Since I've been messing with ponds, I cannot recall ever encountering GSF. Perhaps I should clarify that my main concern are unwanted species in general. Each of my two ponds is supplied by seperate intermittent streams however these two streams join forces just north of the two ponds, with the final dumping ground being the Hudson River.
I can install fish gates to try and control the unwanted species but during spring snow melt and/or heavy rains, I doubt these gates would be effective. Case in point being my
BG pond. I now have eels, LMB and shiners which I'm sure found there way in during heavy runoff times. I suspect bullheads will also find there way in like they did in my other pond.
It would be fun to expert with a YP/SMB only pond but given my situation, I'm curious to hear the thoughts of the experts.
