Just to let you know, if you have a small boat and want to have some fun catching smaller pike, there is a lake called bruce Lake. If you go to the Costco near Iron Mill Mall in Balsac and go straight east and past hwy 9 about 5 km.
Also Mcgregor is great for pike and walleye right alone the rock dam , same again with a boat I have more luck.
Good luck in your search, but there are tons of lakes in southern alberta with pike and walleye just got to learn how to get them
