Squaretail,that's pretty impressive that you caught those Browns in that stretch at this time of the year,water is low and clear.Nice pictures too!
That rock that moved was probably the monster Brown.The question in my mind is did that fish get that large in the stream or did it escape or was released from the nursery?I highly doubt that it grew to that size in the stream,but I guess it will never be known for sure and it's dead meat now so I guess it does n't matter.
Tobassco,the last time I looked several years ago into Trout Creek under the Susquehanna Street bridge there were trout present,appeared to be small natives.But,did n't fish it,the last time I fished there was maybe 40 yrs ago,when it was still a hidden gem in the middle of Allentown.Now it is surrounded with urban blight and not much of a gem.
