I don't know, where are they saying to catch them?
Open your waterway Map, look for where the deeper water is on the map (maybe use a marker buoy if need be), use a float rod (at max depth) or a feeder setup, a #6 - #1 hook and any bread type bait (bread, dough, semolina - or maybe anything a carp might like to eat). Afternoon peak times can be good.
There are gaps in that white fence you can see at one end of the waterway, allowing you to get close enough (casting distance) to the deep water there (about midway along the dirt road).

(There are other areas you can get them too)
