You are very fortunate to have caught a number of 10 to 12" trout at SYR, and to have fished there before the heat wave. I did not think that DFG planted them that large there, and the trout that I have seen there are cookie-cutter smaller planter types. An oldtimer tells me that there are some native trout of that larger size in the SYR that sometimes come out of Gibraltar, but his experience is that you have to be very stealthy to catch these natives. Good job! Where were you fishing? Supposely the native trout are in pools close to Gibraltar. I am fairly new to the area and have a lot to learn, including how to avoid those green sunfish while smallie fishing there with small crawdad/cricket type Rapalas.
