For big lakers, not really anymore. It still has a few left though; my dad hooked a very large one last year but he got a tangle in his reel and it got away. I also caught several 4-5 pounders one day which is a darn good laker in colorado anymore. Average size is your typical 15-20". Numbers can be variable, anywhere from just a few to 40. It is really hit and miss. The trout fishing is also hit or miss. I caught browns, cutts, rainbows, and cutbows there last year up to 17" although most are 12-14". Pike are said to go deep and are very inactive during the winter. The guys who work in the store all say they've never heard of a pike getting iced there before. One day in 90 foot of water over the channel I had a fish bite off though, it struck and acted like a pike on sonar so I assume that's what it was. I wouldn't try to fish for them though.
Best lure is a CHARTREUSE 3" tube jig. Best depths are usually 20-50 feet with 40 being premium. There are a few big lakers left but just not very many. You might put in 100 hours before you hook a large one... and that large one ain't gonna be over 12# probably.
It's worth it. Taylor is one of the most beautiful lakes in the State. Macks are pretty easy to catch, and I've even caught a 16lb 36inch Mack through the ice there. Most are smaller of course, but I usually get at least one over 23" every time I go. Sometimes you can get into the rainbows like crazy if the Macks are not biting. Like TFB said, I have had best luck with Chartruese tubes in this lake. I usually use a 2" but sometimes a 3". Tip with a small cube of sucker meat. They will be on the bottom. A good spot is straight out from the marina, just work your way out untill you find the fish.
Bring the power auger and maybe an extension, if it is the last of jan and it has been a cold winter anyway. You can rent cabins there for cheap if you want to stay overnight or do like I do and camp out on the ice...it gets really cold though
