Supin Fishing Park is located off Khao Talo soi 1/2. Go to the end of the soi, turn right, then take the first left. A small pond but quiet and with friendly staff, usually makes for a very pleasant days fishing.
Update 1st August 2016. Supin have stocked some small Mekong catfish, the ones I saw were around 4kg but put up a great fight against light tackle.
