Halfmoon Creek Fishing Information
Main Section - near Leadville, CO
Halfmoon creek is a gem of a river. It’s scenic, easy to access, and while it can get a bit crowded with campers, there is usually ample fishing opportunities available and it isn’t hard to find your own stretch of water unless your there memorial or labor day weekends. I found you can catch the grand slam in this river with Rainbows, Browns, Cutbows, Cutthroat and Brook trout present in the river. I almost, ALMOST got lucky when fishing this river and it’s a great story. I set up a dry dropper and started on a nice looking bend, and first cast caught a 10” rainbow. Second cast, I caught a 12” brown trout. Third cast I caught a 8” brook trout. I knew this fourth cast was fated for a cutthroat so I walked up to the top of the hole and before I cast I saw a 14” trout sitting in the prime lie and I went for it. He came up for the dry, but a dang 8” rainbow ate my nymph before he got to the dry! I almost achieved a once in a lifetime 4/4 casts for a grand slam. I tried and hooked the cutthroat later for the grand slam, but to have almost done it in my first 4 consecutive casts would have been an incredible story to tell.
All that to say the river is quite productive, fun and in the earlier months (April to June) a small-medium flowing river giving you lots of opportunity to dry dropper or single dry fly fish. Great for beginners and kids, it’s an easy place to fish and a good place to camp, though it can get a bit crowded. The upper reaches are bike in, hike in only and more suitable for solitude or a day fishing with your unruly pup. Enjoy the miles of river and extremely scenic landscape as you fish the creek that flows from the continental divide and the tallest mountain in the state including several other 13k and 14k’ers. Dispersed and paid campgrounds are available. The paid campgrounds need reservations I believe, but I never mess with those places so google it up yourself if that’s your jam.
Note that I fished this in early June during runoff conditions for most of the state and it still fished great. This is one of the few spots (like Willow Creek on the Colorado) that fishes better when in “runoff” like conditions and has some low water issues later in the year.

Hatch Charts
Knowing what flies to use is only have the battle. You have to know when the insects are active on the water and when it's likely the trout are feeding on them. Refer to our hatch charts below to understand when the insect categories and some of the possible hatches on the river.
Midge Hatches
Midges hatch year round, but their importance is from September through winter into April. During the warmer months, the trout often focus on larger insects as they are more active on the water like mayflies, caddis and stoneflies.

View our access map for the Halfmoon Creek and learn public and private access points as well as other notable features around fly fishing this river. We include headwater and confluence data and in an effort to not "hotspot" river access points that are better than others, we list every access point available. This serves two purposes. First, it keeps us from hotspotting, which is just showing the best spots and bringing unwanted and harmful attention to the specific access point. The second reason is while we want to help you catch fish and find great places to explore, we don't want to spell it all out for you. If you get it all spelled out, we're doing the exploring, not you. Missing out on the journey of exploring places to fly fish is one of the more enjoyable aspects of fly fishing. While not everyone has time to go explore everything in person, we provide some of the top level data to help you know if something is worth your time, then pass it off to you to explore and find your own adventure. Now enjoy the info, if you're on this page then this river is worth exploring! Go out and find some memories.
