For someone wanting to just wet a line and not expect too much in the way of size all three in the Springs area "lakes" have lots of stockers and smaller panfish with the occasional surprise holdover or old catfish. Quail and Willow had decent size Pike at one time, but I haven't heard of anything over 30" in a long time. Prospect & Willow even have some saugeye.
For those who don't want to drive or can't afford it, it beats a a kick in the pants or sitting at home. I too have caught a few decent sized trout from Quail a few years ago. Personally, I just wouldn't eat anything out of any of them due to the amount of garbage, goose droppings and other unmentionable items that have been found in them over the years.
