I am taking my daughter to Grand Valley for a 3 day fishing/hiling trip. I have not fished high lakes since I was a teen, and used bait back then. What would you suggest as far as lures or spinners. My understanding is that the lakes are full of small brook trout.
The brookies aren’t likely to be too picky. You’ll need something that can cast well so don’t go too light. I recommend spoons 3/16 oz for lakes like those. They are small, but cast well at that weight. For lures at that weight I’d go with Kamlooper Jr or Daredevil spoons. Red/white or some combination of orange, red, and/or black on brass would be my recommendation. It wouldn’t hurt to throw a 1/4 oz spoon in just in case the fish are deep and you need to let it sink (as is often the case with brookies) but in a lake where they are stunted pretty much anything is likely to work.
Use 4-lb test mono for line and you should be good to go.
