You will catch goldeye all throughout the NSR. I have caught them at the Whitemud creek all the way down to the Legends.
Look for the inflows,backeddies and current breaks always seem to be around there.
I have had better luck from Downtown to Rundle park
If you dont mind a little walk pretty good fishing for all species from the Science Park and upstream from there about a 1/2 mile or so.
If you are back in August and have a fly rod bring it, fly fishing for goldeye with any kind of size 12-14 dry fly is excellent then.
Most of the pics are down around the Science Park but good fishing around Dawson Park and Hermitage Park as well.
