I've fished Lafarge on several occasions (from shore only) and had quite a bit of fun! Bows between 10 - 12 inches and a 9 1/2 lb carp. Good fun, relatively easy fishing.
If you don't mind fishing from a boring looking bank, try the main road side. If you'd prefer something slightly more natural, go to the opposite bank and try near the outlet, casting out a fair way to get over the shallow shelf. Powerbait eggs (orange and chartreuse) with a 3-4 feet leader off of a small lead weight.
