I'd have to agree with jimmy. I fished this lake back in the mid to late 90's, and it was stocked quite well back then (4 - 5 thousand give or take per year). In fact, I remember being out on Alice in my tube, and you could literally "smell" the fish in the air! The setting provides for a much more pleasant and natural experience than the lakes in the city. I always wondered why the stocking numbers were significantly lowered in recent years. I too always thought of Alice being a very popular lake for families and children, and wanted to take my kids fishing there myself.
I understand that the city lakes receive much higher pressure, and the folks from GoFishBC wanted to promote fishing. The city offers the highest population density, and the lakes within it have good shore access. Alice and Browning have decent shore access as well, but other lakes like Stump and Brohm have limited shore access. It's about resources, and getting the biggest "bang for the buck". High density is good and bad. There's more people who are just want to enjoy a nice fishing experience, which means more licenses sold. But there's also more poachers and unethical anglers in the mix.
