Where to Go Middle Fork of the South Platte
Current Reports
SUMMER HOURS 6 am to 6 pm Daily
Report Date: 8/4/2026
Voluntary closure 12 pm - 12 am daily - CPW
Conditions:
Rain continues to be a saving grace up in the South Park region of Colorado. The Upper South Platte River is in dire need of this moisture. This is a morning fishery right now; the earlier the better, even though we are losing sunlight. Fall can't come soon enough to the Middle and South Forks of the South Platte River.
Tomahawk SWA -
Tomahawk State Wildlife Area is the better section of the upper South Platte River right now. This offers more water and a variety of water types. From beaver pond-style bogs to fast riffles and undercut banks.
Badger Basin (Above Spinney) -
While flows have remained steady through our hot and dry summer, the fishing here is going to be very tough. Low water and warm temps are creating a very technical, if even possible, fishery. Fish early or look elsewhere for your day on the water.
Weather:
Short Term -
While we do still have rain forecasted for the day today, this looks to shift in the near future. Take advantage and get out there today! Temps will be in the mid 70's with cloudy skies and rain likely between 3 and 5 pm. Wind is expected to be mild and capped around 11 mph later in the day.
Long Term -
Sun an 80's for most of the week.
Hatches:
Terrestrials are a go-to on the upper sections of the South Platte River. Hopper dropper rigs with big bugs are great all day. If you aren't seeing fish rise to the largest of your dry flies, try a foam ant or beetle, and they just might play. Keep an eye out for the seasonal PMD, Caddis, and Yellow Sallies!
Tactics:
Hopper dropper season is on, and that is a great way to cover water. Keep moving and look for fish. They will be seeking refuge in deeper water, faster currents, and where they can find shelter. Expect them to be spooky.
Tips:
Because the water is low, the temps are hot, and the sun will be high in the sky, a stealthy approach is key. Make sure you see them before they see you. Sneak up slowly and softly from behind, watch how they are feeding, and THEN make a cast.

River Details
About Alma SWA
Middle Fork of the South Platte River finds its headwaters above Hoosier Pass. Water is diverted from the Breckenridge area and passed through a tunnel under Hoosier Pass into Montgomery Reservoir. This augments the flow particularly in the early summer.
About Tomahawk
Tomahawk is the Middle Fork of the South Platte River. This stretch of the river is a great place to find solitude from the crowds. Summer and fall are a great time of the year to throw big hoppers to eager brown trout. In the summer, bring insect repellent because the mosquitos can get bad. In the fall, bring heavy leaders because large browns come out of their typical hiding spaces and move up river from Spinney to spawn.
This is an area we specialize and are permitted to guide, so give us a shout if you have any questions or if you are interested in allowing one of our Orvis-Endorsed guides show you how best to conquer Middle Fork of the South Platte.
